These general purpose power supplies can be used to fulfill all the 120 Vac, 24 Vac (Class 2), and 24 Vdc power requirements needed inside a building automation (BAS) panel, in addition to on/off control, equipment overcurrent protection, power indication, high/low voltage separation, and convenience outlets. They are also useful for many applications outside of BAS. They range in power output from 40 VA to 500 VA for the A/C outputs and 300 mA to 1 Amp for the D/C outputs. There are a variety of mounting options including track mount and self-contained in a NEMA 1 enclosure for mounting inside or outside of panels. Most models are UL Listed and CE approved.
