Valmu lighting transformer is the clock-controlled central unit of the 48VAC lighting system. A total of 75 lights can be connected to a safe low voltage network in one 2000 VA transformer. The lights are divided into three circuits, each with its own switch, quick fuse and indicator light. Two of the circuits are controlled by an Orbis Data Log clock switch that can be timed directly from the transformer or by a phone application via Bluetooth. One lighting circuit is the so-called safety light circuit, i.e. power stays on all the time.

The transformer has a main switch. Thanks to the indicator lights, it is easy to see from the transformer whether power is coming to the transformer and to all circuits. Lightweight and efficient Valmu transformer can be hung on the wall from the suspension loops. The connection is fast thanks to the spring connectors. Strain relief is done on the transformer bar. Valmu is made in Finland.
