Lab Bench DC Power Supply Variable, 900W Laboratory Switching Power Supply Unit 30V 30A Adjustable Digital Source 200V 5A Voltage Stabilizer for Laboratory,Test Faulty Motor,Repair(60V 20A 1200W)

Programmable DC Power Supply You can connect the dc power supply variable to your computer via the back RS232 port to precise control or upgrade your dc power supply. Upgrade High-precision Encoder Knob Just "set" voltage and current instead of "adjust". The encoder switch replaces the potentiometer switch, the digits are switched by pressing the knob and each digit can be set in the range 0-9 by turning the knob. Makes work easier and more efficient! Stable Output, Auto Switch C.C/C.V Mode This variable DC power supply is a low noise, low ripple adjustable high power continuous output power supply that can work at full load for long periods of time. Constant voltage and constant current modes can be switched automatically. Multiple Protection, Intelligent Cooling Fan, Reliable and Safe The DC power supply has built-in overvoltage protection, overcurrent protection, overheating protection and termination protection. When the operating temperature of the DC power supply exceeds 122°F/50°C, the fan will turn on intelligently to dissipate heat effectively and extend the life of the device. DC power supply has shock absorbing rubber feet at the bottom for safer and more stable use.
