HY3030E Variable Power Supply UnitHY3030E variable power supply unit offered by Mastech is a highly stable regulated DC power supply unit with adjustable output voltage and output current limitation. The power supply unit supplies DC to electronic devices and circuits with the voltage of 0 to 30 Volt and current of 0 to 30 Amperes. One can control the set values for current and voltage using LED indicators. Measurement parameters are adjusted with the help of separate potentionmeters for current and voltage, and separately for accurate and rough adjustment. The lower part of the device's front panel holds output voltage terminals and the bonding point. Slots with screw clamps enable the use of wires with unipolar plugs or without any plugs at all. In the case of the latter the conductor is securely fixed using a screw clamp. The device is protected against short-circuits and excessive voltage. A special system will help protect the power supply unit from failures associated with defects in the circuits powered by the device and with incorrect operation by the service personnel. The internal circuit of HY3030E is built on a pulse transformer that is widely known for its high efficiency.
