The 3241.5 laboratory DC voltage regulator is a linear laboratory power supply for precise adjustable DC voltage supply. The unit provides an output voltage of 0 to 300 VDC and an output current of 0 to 0.4 A. With an output power of 120 W, the DC voltage regulator is suitable for laboratory, testing and development applications.

The input voltage is 230 VAC / 50 Hz. Input and output are galvanically isolated and designed as floating. This allows the unit to be used flexibly in different test setups where safe isolation between the mains supply and the output is required.

As a linear regulator, the unit provides automatic operating mode switching between CV mode for constant voltage and CC mode for constant current. The integrated voltage and current regulation enables controlled adaptation to the connected load. The unit is also short-circuit-proof.

The CV stability for a load change from 0 to 100 % is 10 mV. The residual ripple in CV mode is also 10 mV RMS. The settling time is 100 µs. A test button is provided for checking the preset current limit.

The input connection is made via a 3-pole mains cable with European safety plug. The output is provided via 4 mm safety sockets. The device is designed as a benchtop unit with convection cooling and has protection rating/class IP30 / I.
