VR battery modules are used to work with single-phase OnePower Pro UPS, single-phase and three-phase EcoPower UPS, as well as with other devices and uninterruptible power sources requiring a standby storage battery for 24, 36, 48, 72 or 240 V.
When battery modules work together with uninterruptible power supplies, the batteries are automatically charged in UPS stand-by mode.
VR battery modules do not require any permanent presence of service personnel, as they are equipped with stationary lead-acid sealed maintenance-free batteries.
