Power supply unit HY3002 provides electronic devises and schemes with power supply by continuous voltage in the range from 0 to 30V and by current in the range from 0 to 2 A.
Features:
- Parameters adjustment is made by means of potentiometers. There are two adjusters to control each parameter (Coarse/Fine).
- Output current value and output voltage value are displayed on 3-digits red colour LED-indicators.
- There is a fault protection of the secondary circuit in the power supply HY3002. In case of shutdown, appropriate LED indicators flash on by current or by voltage.
- Output terminals, from which one can turn off the voltage and ground connector, are in the bottom of power supply faceplate HY3002.
- Power supply is made from the alternating current network 220 V. To turn on/off power supply source HY3002 the big key switch with safe position fixation is used.
