PROGRAMMABLE DC POWER SUPPLY – PPS SERIES
- 4 digits LCD display for voltage and current
- Constant voltage and constant current operations, auto CV/CC switch
- Front panel operation: preset voltage and current, output ON/OFF
- Multiple protections: OVP, OCP, OTP and OLP
- Low Ripple, High stability
- Communication: RS232 and RS485 interface, Support ModBus-RTU commands.
TEKLAB Programmable DC power supply with high efficiency, high accuracy and high stability. High gain amplifier circuit design makes this series with fast response Improvement on circuits. Active air duct design and optimized cooling channels effectively reduce temperature rise. Over Voltage Protection, Over Current Protection as well as Over Temperature Protection keeps this series and their load safe from unexpected conditions
