Topkko DC Power Supply 0-400V 0-1A 400W

Industrial High-Voltage Output (400V – 1000V / 1A)

High-Voltage Specialized Design: Covers an ultra-high voltage output range from 400V to 1000V (1A current), making it ideal for capacitor withstand voltage testing, photovoltaic inverter testing, insulation material testing, and high-voltage component burn-in tests.

Multi-Protocol PC Communication Interfaces (RS-232 / USB / RS-485)

Comprehensive Connectivity: Equipped with RS-232, USB, and RS-485 communication ports for flexible computer and PLC integration.

Automated System Control: Supports remote monitoring, automated parameter programming, data logging, and industrial network integration (e.g., Modbus protocol over RS-485).

High-Brightness 4-Digit LED Display

3-Row Simultaneous Display: Features a large LED digital screen displaying Voltage (V), Current (A), and Power (W) simultaneously in real time.

C.V / C.C Status Indicators: Includes dedicated LED lights for Constant Voltage (C.V) and Constant Current (C.C) modes with automatic crossover.

Smart Controls & Preset Storage

3 Quick Memory Buttons (M1 / M2 / M3): Dedicated front-panel storage keys allow users to save and recall 3 commonly used high-voltage presets with a single press.

Precision Digital Encoder Knobs: Features VOLTAGE and CURRENT encoder knobs for fine digit-by-digit tuning, preventing sudden large jumps in high-voltage settings.

Comprehensive High-Voltage Safety Protections

Hardware OVP / OCP Protection:

OVP (Over-Voltage Protection): Triggers an alarm and cuts off output power immediately if the voltage exceeds the set safety limit.

OCP (Over-Current Protection): Cuts off output rapidly when current exceeds the set threshold to prevent breakdown or damage to the device under test.

Independent OUTPUT Switch: Enables users to configure high-voltage parameters safely prior to switching on the output, reducing the risk of high-voltage arcing.

LOCK & Mute Key: Press LOCK to lock panel keys during high-voltage operations to prevent accidental misoperation; hold for 5 seconds to toggle buzzer sound on or off.

Standard High-Voltage Safety Terminals & Thermal Management

Insulated Safety Terminals: Front panel includes insulated positive (+), negative (-), and ground (GND) binding posts designed to ensure safety during high-voltage operation.

Industrial Cooling Structure: Side ventilation slots paired with an internal smart temperature-controlled fan maintain system stability and safety during continuous high-voltage operation.
