15KW Programmable DC Power Supply (380V input, 0-50V, 0-300A, 15KW output)

Input Voltage: 3-phase AC 380V ±15%, 50/60HZ (default 3-phase 380V input)

Power Factor: ≥0.96, tested at load above 20%.

Output Voltage: DC 0~rated value V

Output Current: DC 0~rated value A, can be preset

(Maximum voltage 1500V, current 300A, power within 15KW can be customized)

Source Voltage Regulation Rate: voltage regulation ≤ 0.5%; load regulation rate: constant voltage ≤ 0.5%; constant current ≤ 1%.

Ripple Voltage: Total ripple voltage Vpp≤0.5%; overall machine efficiency: >92%.

Parameter Display: 61*42mm high-definition LCD display.

Display Accuracy: voltage ≤ 0.5%, current ≤ 1%.

Start-up voltage overshoot: ≤0.5%.

Protection: Output overvoltage, overload, short circuit, machine overtemperature protection, overtemperature protection threshold (80~85)℃

Heat Dissipation Method: Intelligent temperature-controlled fan for heat dissipation. The fan starts spinning when the temperature is higher than 40°C, effectively extending the fan life.

Fault Display Mode: When the power supply fails, the “fault” indicator light lights up and alarms.

Setting Method: Digital encoder input type, the setting value has power-off memory.

Communication Interface: optional RS485, RS232, CAN interface.
