Specification

Features

1. High-Voltage Output: The DC power supply delivers adjustable 0–300V output with up to 600W power, providing flexible power delivery for electronics testing, development, and maintenance.
2. Adjustable Output Control: Voltage, current, slope, and time-cycle parameters can be programmed to create controlled output sequences for repeatable testing and automated operation.
3. Accurate Load Control: The variable DC power supply uses dedicated load-side voltage sensing to detectactual load voltage and compensate for voltage drops, helping maintain precise output control.
4. Comprehensive Protection: Overvoltage, overcurrent, and overtemperature protection help reduce the risk of damage to the power supply and connected equipment during abnormal operating conditions.
5. Flexible Remote Control: RS-485, RS-232 interfaces enable the DC power supply to work with external control systems, while MODBUS supports automated operation and system integration.
6. Compact Design: The power supply combines a compact body with an approximately 1.8kg weight, making it convenient for laboratory benches and space-limited workstations.

Tips: How to Use a variable DC power supply safely and correctly?

• Output Setting: Set the required voltage and current limit before connecting the load. Check the displayed values and ensure they match the load’s rated input range.
• Load Connection: Verify the output settings and polarity before connecting the load. Disconnect the load before making significant voltage adjustments or changing the output range.
• Current Limit: Set the current limit slightly above the load’s expected operating current. If the load exceeds this limit, the DC power supply may enter current-limiting or CC mode.
• Protection: If OVP, OCP, or OTP protection is triggered, disconnect the load and check for short circuits, incorrect wiring, or excessive current before resuming operation.
• Series Connection: When connecting DC power supplies in series, verify output isolation, polarity, and voltage ratings. The supply with the lowest current rating determines the usable current.
• Output Monitoring: Monitor the displayed voltage and current during testing. Changes in output current can help identify abnormal load conditions or operation near the current limit.
