30-Second Fit Check

Need a silent, high-precision DC source on your bench? Models cover 0-40V to 0-750V, with currents up to 60A.
Output power: 320W to 1500W across the series; up to 92% efficiency with active PFC.
Constant voltage (CV), constant current (CC), constant power (CP), plus internal resistance simulation.
Colour 4.3" TFT touch panel with two rotary knobs; preset set values without energising the output.
Comprehensive protection: OVP, OCP, OPP, OT; 40V models are SELV compliant.

What It Is + Why It Matters

Microprocessor-controlled bench DC power supplies for R&D, industrial automation, and laboratory testing.
Integrated function generator (sine, square, ramp, arbitrary etc.) plus an editable 99-sequence arbitrary generator for complex test routines.
Internal resistance simulation enables realistic source behaviour; low residual ripple and a fast discharge circuit (Uout < 60V in ≤10s) add operational safety.
Multiple galvanically isolated interfaces – analog (0-5/10V), USB, Ethernet (SCPI & ModBus RTU) – ensure easy system integration.

Note: Remote sensing is available to compensate voltage drop. Use twisted sense wires and observe polarity. Ensure adequate ventilation (min. 30 cm rear clearance).

Best for / Not for

Best for: Laboratory experiments, automated test systems, industrial 24V/48V DC supply, electroplating, battery charging (with proper settings), and semiconductor testing.
Not for: Applications requiring AC output, direct parallel operation for current sharing without external controls, or environments without adequate ventilation.

Selection Checklist + RFQ

Choose voltage/current model within 40V-750V / 4A-60A to match your load requirement.
Verify total continuous power demand ≤ rated model power, considering any derating at high ambient temperatures.
Select interface settings: analog range (0-5V/0-10V), Ethernet IP mode, and required remote control protocol (SCPI/ModBus).
Plan for 30 cm rear clearance and, if rack mounting, ensure support rails are installed.
