This transformer transmits alternating current. The design of the housing is more like a contactor than a classic transformer and thus enhances the control cabinet. The input voltage is 230 VAC or 400 VAC and can be adjusted by +/-15 VAC. The supply comes from a 1-phase network or between 2 phases of a 3-phase network. On the output side, 2 independent 115 VAC at 25 VA are available via a double winding. Using jumpers, the output voltages can optionally be connected in parallel to increase the power or in series to increase the voltage. The mains frequency is 50/60 Hz. It is attached to a mounting plate with 4 screws. An LED display provides information about the status.
