PowerMax PMTS-50, 240/120 VAC 30A automatic transfer relay
PowerMax’s PMTS-50 is an 120/240 VAC split-phase, 30 Amp automatic transfer switch. When plugged into shore power or a generator it will automatically provide AC power from that source to all AC appliances. To operate your appliances from an on-board generator, simply start the generator and the PMTS-50 will (after 20-30 seconds) automatically transfer to the generator to power the AC appliances. The time delay allows the generator voltage to stabilize.
The PMTS-50 can be mounted in any position. It is best to install the PMTS-50 as close to the generator and shore power cord entrance as possible in order to minimize Voltage drop across the wire.
Note: The PowerMax spec sheet claims 50 Amp for this transfer switch. However, based on the relay/contactor inside we believe 30 Amp should be the safe/proper rating.
