OutBack > Autotransformer with Auto-Disconnect

Manufacturer Part Number: PSX-240-Relay

The OutBack PSX-240-Relay has all the attributes of the PSX-240 and more. Equipped with an internal relay with external controls, the transformer can be disconnected from the system by a simple 12-volt signal. In customized systems, which may alternate between both split-phase and three-phase sources, this protective switch allows your PSX-240-Relay to be easily and safely removed from conflicting voltages. Use for 120 or 240 Vac, 60 Hz systems only.

The PSX-240-Relay must be connected to the AC output circuit of the FX system and is intended for installations that include the following:

• An installation with two or more OutBack FX Series Inverter/Chargers wired to produce split phase 120/240 VAC.
• The FX system is programmed using “OutBack” Stacking (not “Classic” Stacking).
AC input source to the FX system is either two in-phase 120 VAC circuits, 120/240 VAC split phase, or two phases of a 120/208 VAC wye-connected 3-phase source.
