Working Principle

Core Function Features

1. Closed-loop high-precision voltage & current dual regulation mode, automatic cross-over between constant voltage (CV) and constant current (CC)
2. Standard isolated analog control interface (0–10 V analog signal corresponds to full-scale voltage/current adjustment)
3. Optional communication expansion modules: GPIB, LXI LAN, USB full digital remote control
4. Built-in output short-circuit continuous protection, auto-recovery after fault clearance
5. Over-temperature protection with staged fan speed adjustment
6. Front-panel local manual adjustment lock function to prevent accidental parameter modification
7. Remote sense terminals eliminate voltage drop error from long output cables

Advantage Highlights

1. Ultra-compact 1U high power density design, saves cabinet rack space for multi-unit stacked integration
2. Ultra-low ripple noise performance, meets precision semiconductor testing requirements
3. High full-load energy efficiency reduces long-term operating power consumption
4. Multi-layer electromagnetic shielding structure, strong anti-interference capability for industrial automation environments
5. Wide temperature operating range without performance derating below 40°C ambient
6. Modular communication expansion design supports seamless integration with automated test equipment (ATE) systems

Applicable Industries

Installation Requirements

1. Mount on standard 19-inch industrial electrical rack, reserve ≥150 mm rear ventilation clearance
2. Install horizontally only; vertical mounting is prohibited to avoid heat sink heat accumulation
3. AC input wiring must match rated current wire gauge (minimum 2.5 mm² copper wire) with dedicated grounding wire
4. Remote sense wires must be twisted shielded cables, routed separately from power output cables
5. Communication signal cables require 120 Ω terminal matching resistors for long-distance wiring

Operation & Maintenance Precautions

1. Do not operate without load for long durations; no-load operation exceeding 2 hours triggers automatic low-power standby
2. Regularly clean front air intake filter every 3 months to prevent fan blockage and overheating faults
3. Disconnect AC input power before opening chassis for internal inspection to avoid high-voltage electric shock hazards
4. Do not connect capacitive loads exceeding 1000 μF without pre-charge configuration
5. Ambient operating temperature exceeding 50°C causes automatic power derating to 70% rated output
