Laboratory power supply
BR 351
Characteristics
General data
The laboratory power supplies of the BR series allow continuous adjustment of the output voltage from 0 to 250 Vac and are used for testing electrical circuits. The output voltage is galvanically isolated from the mains, and the power switch is illuminated. The housing features recessed, space-saving side handles and can be stacked to save space.
Benefits
› Non-inherently short-circuit proof
› Analogue current and voltage indicator
› Output circuit breakers may be operated from the front
› Carry handle, mains cable with safety plug, shockproof socket for portable application
