What It Is + Why It Matters

Microprocessor-controlled programmable desktop DC power supply for R&D, laboratory testing, electronic device validation and production inspection.
The flexible power-regulated output stage allows higher voltage at lower current or higher current at lower voltage, while staying within the rated output power.
Voltage, current and power can be adjusted continuously from 0-100%, whether controlled manually or remotely.
The blue LCD display shows set values, actual output values and device status clearly in one place.
Memory for 9 preset groups helps reduce setup time for repeated voltage, current, power and protection settings.

Note: For best model selection, confirm the required voltage range, current range, continuous power demand and preferred control method before ordering.

Model Selection Checklist

Selection Factor	Recommended Check	Why It Matters	Example Choice
Voltage Range	Choose 40V, 80V or 200V output range.	The voltage rating must cover the maximum required load voltage.	Use a 200V model for higher-voltage DC testing.
Current Range	Check required continuous and peak load current.	Current capacity determines whether the supply can support the intended operating point.	Use a 40A model for low-voltage, high-current applications.
Power Rating	Select 160W, 320W or 640W class.	Voltage and current combinations are limited by the model’s total rated output power.	Use a 640W model for higher continuous power demand.
Remote Control	Decide between analog, USB or Ethernet control.	Interface selection affects automation, data recording and integration into test systems.	Use Ethernet or USB for digital remote control; use analog for 0-10V control systems.
Protection Limits	Configure OVP, OCP and OPP before testing.	Protection thresholds help reduce risk to the power supply and connected load.	Set OVP slightly above the expected operating voltage for sensitive electronics.

Best for / Not for

Best for: Programmable DC bench testing, electronic device validation, R&D power supply tasks and automated test setups.
Best for: Applications requiring compact size, wide AC input, active PFC, analog control, USB control and Ethernet connectivity.
Not for: Applications requiring AC output or output power above 640W.
Not for: Loads requiring voltage, current or power combinations beyond the selected model rating.

RFQ Preparation Tips

Confirm the required output voltage range: 40V, 80V or 200V.
Confirm required output current and continuous power demand.
Specify whether analog, USB or Ethernet remote control is required.
Define protection requirements such as maximum allowed voltage, current and power.
Share load type, operating duty cycle and ambient temperature for more accurate model selection.
