If you’re a system integrator, panel builder, procurement lead, or electrical engineer, you don’t need another “what is a DIN rail power supply” overview. You need a fast, spec-true way to select a compact DIN Rail Power Supply that will survive real cabinets, pass your project’s compliance gates, and get you to an RFQ without rework.
This BoFu guide is built around the TPS010–100W GP Series—a compact, convection-cooled, IP20 DIN rail PSU family with wide AC/DC input and built-in protection. Use it to match wattage, 12V/24V adjustable outputs, cabinet thermal reality, and documentation needs—then request pricing/lead time from the TPS US DIN-rail catalog.
Tip for procurement: add the likely models to your quote list first, then confirm the exact output setpoint, ambient temperature, and load profile in the RFQ notes.
The TPS010–100W GP Series is a practical choice when your project needs a compact, cabinet-friendly DIN rail supply for: Building automation panels, Industrial automation I/O and PLC distribution, and LED lighting control cabinets—especially where fanless operation matters (dust, maintenance, noise, service intervals).
It is most compelling when you need: a wide AC/DC front end (90–264VAC and 120–370VDC are commonly required in mixed facilities), a simple IP20 cabinet-grade enclosure, and protection behavior that auto-recovers from common field events: Overload Protection, OVP (over-voltage protection), and OTP (over-temperature protection).
If you’re building full cabinets, these two resources help you align PSU selection with enclosure layout and integration workflow: industrial control cabinets for automation and build-to-print control panels (checkpoint process).
Think of this series as a “global-input, cabinet-grade, fanless” DIN rail platform in four frame sizes (10W, 30W, 60W, 100W), with adjustable output variants in 12V and 24V classes. For many teams, the purchase decision hinges on five factors: input compatibility, output headroom, thermal behavior, protection behavior, and the paperwork you need to pass internal/external compliance gates.

Below is a practical model map based on the GP series ordering structure. The key “gotcha” to watch: the frame name (e.g., “100W series”) doesn’t always mean every voltage variant delivers the same wattage. In many compact DIN rail families, the 12V variant can be current-limited to a lower wattage than the 24V variant—so always match by rated output power and current, not label alone.
| Model | Output (Adjustable) | Rated Current | Rated Power | Efficiency (typ.) | Typical use |
|---|---|---|---|---|---|
| TPS010-GP12V | 12–15V | 0.85A | 10W | 80% | small control loads, sensors, relays |
| TPS010-GP24V | 24–28V | 0.42A | 10W | 80% | 24V signaling, compact I/O islands |
| TPS030-GP12V | 12–15V | 2.5A | 30W | 84% | higher 12V demand, small actuators |
| TPS030-GP24V | 24–28V | 1.25A | 30W | 85% | standard 24V cabinet power (small) |
| TPS060-GP12V | 12–15V | 4.5A | 54W | 87% | distributed 12V loads, field devices |
| TPS060-GP24V | 24–28V | 2.5A | 60W | 87% | mid-size 24V automation cabinets |
| TPS100-GP12V | 12–15V | 6A | 72W | 87% | heavier 12V rails, cabinet distribution |
| TPS100-GP24V | 24–28V | 4.2A | 100W | 89% | PLC/I-O panels, 24V distribution backbone |

For most industrial control ecosystems, 24VDC is the default distribution rail (PLC, sensors, safety relays, valves), while 12VDC shows up in networking, certain embedded controllers, and accessory rails. The GP series supports adjustable setpoints in both classes—use that adjustability to compensate for wiring drops and load requirements, but keep your setpoint inside the defined adjustment window.
If you’re converting from facility power to 24V cabinet distribution and want a practical checklist, this companion guide can help: 24V DIN rail power supply guide (120VAC → 24VDC).
“Nameplate watts” rarely survives contact with the cabinet. In a real enclosure, you’ll see higher ambient, clustered heat sources, cable congestion, and load steps. Build in headroom for: (1) temperature derating in hot cabinets, (2) short peak loads or inrush for connected devices, and (3) future expansion (the change order you’d like to avoid).
A practical rule: size your supply so that your typical steady-state load lands in a comfortable mid-band, not at the edge. That improves thermal margin, helps stability under transient events, and reduces nuisance trips on overload protection.
The series includes built-in protection (Overload Protection, OVP, OTP) with auto-recovery behavior. That’s a win in field cabinets where a wiring fault or temporary thermal event shouldn’t require a truck roll just to reset power. For loads like motors/solenoids, LED drivers, or high-capacitance DC rails, the “shape” of current demand matters—so tell TPS what your load looks like in the RFQ.
If your project is larger (200W+ distribution or 24–48V bus sizing), you may also want: switching DC power supply selection (24–48V, 200W–1000W).
DIN rail power supplies live or die by mechanical fit and serviceability. The GP series is designed for TS35-style rails (common in US panels), and standardized rail dimensions are governed by IEC 60715. If your customer references “DIN rail compliance,” this is the authoritative baseline: IEC 60715: standardized mounting on rails.
In cabinet builds, most power problems are installation problems: loose terminations, under-sized conductors, poor grounding paths, and routing that injects noise into sensitive control lines. Best practices:
If you’re building harnesses for repeatable assembly and fewer field errors: custom cable assemblies & wire harness services.
Fanless Convection Cooled supplies reduce maintenance, but they require airflow paths. Don’t stack them hard against heat sources or block natural vertical airflow with wiring bundles. Plan layout early, and—if your cabinet requires custom enclosures—optimize geometry and finishes for heat and corrosion resistance: custom sheet metal enclosures and powder coating for electrical enclosures.
For US panel projects, “CE / RoHS” language often shows up in global programs, exported equipment, or internal corporate standards—even when the final installation is in North America. The GP series is positioned with CE and ROHS alignment, and the right way to manage this is simple: request the documentation set you need before you place the order.
CE marking for power supplies commonly aligns with EU directives such as: Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU. If your customer asks “show me the directive references,” these are the canonical sources.
For hazardous substance restrictions, the standard reference is the EU RoHS directive: Directive 2011/65/EU (RoHS). In an RFQ, ask for the supplier’s declaration and traceability approach (especially if your end customer requires it as part of the PPAP-like document pack).
US end customers may require UL/cULus (or another NRTL) depending on the application, panel standard, and inspection authority. If that applies, call it out explicitly in the RFQ so TPS can confirm the correct compliance path and paperwork for the exact model/variant. The fastest way to align expectations is to send: the model(s), quantity, use case, enclosure environment, and your required compliance list in one message.
If you need help aligning compliance with test strategy (EMC/safety) in a system context, you can also reference: power selection for US compliance.
Copy the checklist below into your RFQ so engineering + procurement + panel shop stay aligned. This is the quickest path to a clean quote and fewer follow-up cycles.
Start by estimating steady-state 24V load current and adding margin for peaks, temperature, and future expansion. For small panels, 30W can be enough; for PLC/I-O distribution and heavier cabinets, 60W or 100W is more typical. If you’re unsure, shortlist two adjacent wattage options and request a quote—include your ambient temperature and load profile.
Yes—this family is designed around wide input operation that supports common AC mains and DC bus conditions. For RFQ accuracy, specify your real input source (nominal voltage and expected range) and the environment (cabinet max ambient).
The GP series includes built-in protection behavior commonly needed in industrial panels: Overload Protection, OVP, and OTP, with auto-recovery behavior intended to reduce downtime after transient events. Always describe your load type in the RFQ if you have inductive loads, large capacitive loads, or frequent power cycling.
IP20 is a typical rating for in-cabinet components where the enclosure provides the environmental barrier. “Double insulation” is a safety design approach; your final panel’s safety and compliance still depends on the complete system design, grounding, wiring, spacing, and verification testing.
Model shortlist, quantity, input type, output setpoint, load current and load profile, cabinet max ambient, and any compliance documentation requirements. Use the copy/paste checklist above, then submit it through the DIN-Rail Power Supply collection page.
If you want the fastest path to a clean selection and a clean quote, do this: shortlist the likely GP models (12V or 24V, 10–100W frame), then send your load profile + cabinet ambient + compliance needs in one RFQ.
