Description

30-Second Fit Check

Need high voltage in a space‑saving rack? Output is 0–750 V, rated 0–12 A.
Rated power: 3000 W with autoranging (U/I/P) – full current available across a wide voltage band.
AC input: 180–264 VAC, 1ph+N or 2ph, 45–65 Hz with active PFC (derates to 2500 W below 207 VAC).
Protection: OTP, OVP, OCP, OPP, PF with configurable thresholds.
Built‑in discharge circuit reduces output to <60 V within ≤10 s after DC off – critical for 750 V safety.
Ultra‑low height: only 1U (44 mm); weight approx. 11 kg.

What It Is + Why It Matters

Ultra‑compact 1U programmable DC power supply delivering 3000 W autoranging output at up to 750 V for high‑voltage industrial test, burn‑in, and ATE systems.
Autoranging output stage provides up to 750 V at lower current or up to 12 A at lower voltage, covering diverse test profiles with a single unit.
Built‑in discharge circuit safely reduces output voltage after shutdown – essential for operator protection when working at 750 V.
Internal resistance simulation and remote sensing are built in, eliminating external decade boxes or sensing modules.
Share Bus allows simple parallel connection of identical units to scale current capacity for applications needing more than 12 A.
Galvanically isolated analog 0‑5/10 V, USB, and Ethernet interfaces provide full remote control via SCPI and ModBus RTU.

Note: DC output terminals are on the rear panel. The discharge circuit automatically activates after DC output is switched off – always verify voltage has decayed to safe levels before handling connections.

Best for / Not for

Best for: high‑voltage industrial testing, insulation testing, photovoltaic inverter validation, DC‑DC converter testing, semiconductor burn‑in, and automated ATE where 1U density, 750 V capability, and autoranging flexibility are critical.
Not for: applications needing output voltage above 750 V, current beyond 12 A from a single unit, or sustained power above 3000 W (2500 W if AC <207 VAC).

Selection Checklist + RFQ

Confirm required output range fits 0–750 V, 0–12 A, and max. 3000 W (2500 W if AC <207 VAC).
Verify AC mains: 180–264 VAC (single‑phase or two‑phase).
Choose remote control method: analog (0‑5/10V), USB, or Ethernet (SCPI/ModBus).
If parallel operation is needed for higher current, design the Share Bus connection correctly.
Plan rack depth (≥500 mm) and cooling; the discharge circuit provides essential operator safety for 750 V setups.
