Products Description




PPM series are high precision programmable linear DC power supply with single output, output power rated from 90W to 375W with various model numbers. The output voltage is available from 18V 30V 36V 60V 75V 120V 150V 300V 500V.

The high precision programmable linear DC power supply features low regulation 0.01%, low ripple and noise 1mVrms.  RS232 interface is configured for each programmable linear DC power supply, supporting SCPI commands.

A special feature of the high precision programmable linear DC power supply is lithium battery curved charge mode. It allow users to set high and low charging voltage/current during different charging stages.

The high precision programmable linear DC power supply has been upgraded to have data record function through software, as well as RAMP output.
