SHOT-U_OUTPUT-I_OUTPUT-N_OUTPUT-UKHL4 SINGLE-CHANNEL OPERATING CURRENT CABINET
The cabinet is equipped with an LCD display and LED indication on the door, indication of the state of switching devices, RS485 ModBus RTU interface, discrete status outputs. Contains one step-down low-frequency transformer, protective input and output circuit breakers (can be optionally replaced with a disconnector), a rectifier power unit, a reverse diode (parallel operation is allowed).
