This 30-watt bench supply are designed for general laboratory use. The constant-voltage,constant-current output allows operation as either a voltage or current source. The changeover occurs automatically, based on the load. It has has two ranges, allowing more current at a lower voltage.
This model also features overload protection. A continuously acting constant current circuit protects the power supply against all overloads including a direct short placed across the terminals in a constant voltage operation.
Features
- Dual range
- 10 turn pots
- Constant Voltage (CV),
- Constant Current (CC) modes.
