Should be fine. I've got 2.1A of 24VDC, which sole purpose in life now the old controller is gone, is to power a few relays and sensors. If need be, I can upgrade it or fit a second supply.

I've ordered a suitable ABB contactor that only takes 3.5W coil power from RS, as I get free next day delivery. I even ordered one with a NC Aux contact, which I can use to switch in a drain resistor for the capacitor, rather than have the resistor continually warming things up.
