PowerVerter APS units automatically sense and switch AC output between outside power (utility or generator) and battery power when no AC power is available. Ideal for use as mobile power systems or stationary UPS/emergency power supplies. Models include a technically-advanced 3-stage battery charger for quicker recharge, plus protection against over-charge and over-discharge to ensure a longer service life from batteries. High-efficiency output is frequency-controlled to support delicate loads. APS series inverters do not include batteries; users supply batteries to determine their own runtimes. |
