Programmable DC Bench Power Supply RS232/RS485 30V–300V Automatic Voltage Regulator KPS Series
KPS Programmable DC Bench Power Supply (RS232 / RS485)
The KPS series programmable DC bench power supply is a high-power digitally controlled solution designed for laboratory testing, industrial automation, electronics development, and production environments. With RS232 / RS485 communication interfaces, the unit supports precise remote control, automation, and seamless integration into test systems.
Voltage and current can be smoothly regulated from zero to rated values using encoder adjustment and software control. A high-resolution digital display allows real-time monitoring of output parameters. The switching design delivers high efficiency, fast transient response, low ripple, and stable full-load operation under demanding conditions.
Multiple protection mechanisms help ensure reliable long-term operation by guarding against overvoltage, overcurrent, overload, overheating, and short-circuit faults. The compact construction supports bench operation and rack installation, making this series suitable for telecom, automotive electronics, battery charging, electroplating, semiconductor research, and education labs.
Remote adjustment and integration into automated test systems.
Smooth regulation from 0 to rated voltage/current for precise setups.
Stable constant voltage and constant current regulation under changing loads.
OVP, OCP, OPP, OTP for safe operation and long service life.
