Purchased a Panasonic VL-SWD275 video intercom from Australia to replace my 2-wire intercom in the US to avoid rewiring the whole house with a 4-wire system.
The Panasonic VL-SWD275 requires 220v and 24v DC at 6amps. I purchased and installed a Zerone AC 100-240V to DC 24V 6-9A Switching Electricity Supply Module 150W step-up transformer into the outlet thinking I could wire the non-polarized main monitor directly to the DC output of the transformer.
I've read on this site that a non-polarized device like a clock wouldn't care if it was rewired with a polarized replacement wire and plug of the same gauge.
The Panasonic VL-SWD275 kit includes a 220/240v power supply that has a non-polarized AC input, and a 24v DC -/+ terminal output. The main monitor includes 2 power input terminal wire ports, but says the wires must be non-polarized!!!
Can I power the VL-SWD275 with the red and black +/- 24v DC output wires from the Zerone step-up transformer and omit the power supply in the kit????
