Add Batteries to Empty Cabinets to Extend Runtime of SV-Series UPS Systems This external backup battery pack consists of two battery cabinets that require 40 user-supplied CSB HRL12500W (or equivalent) sealed lead acid batteries to give your Tripp Lite SV-Series 3-phase UPS system more runtime. It uses a +/-120VDC configuration and must be hardwired to a compatible UPS system. You can also connect more battery packs in parallel to increase runtime even longer. A UL-listed DC circuit breaker protects against too much current. The EBP240V5002NB is compatible with all Tripp Lite UPS models that begin with SV20, SV40, SV60, SV80, SV100, SV120 and SV140. Designed and Constructed to Ensure Consistent Power for a Long Time This 120V UPS battery pack is made from heavy-gauge welded steel with a baked powder-coated finish that protects the cabinets from chipping and corrosion. The hinged cabinet door locks to prevent tampering and to facilitate easy access to the internal batteries. User-supplied power output cables feed into the cabinets through conduit knockouts built into the cabinets’ exterior. Front and rear vents allow the free flow of warm air out of the cabinets to maintain cool internal temperatures. Sturdy metal casters allow you to smoothly roll the backup battery pack into position. TAA-Compliant for GSA Schedule Purchases The EBP240V5002NB is compliant with the Federal Trade Agreements Act (TAA), which makes it eligible for GSA (General Services Administration) Schedule and other federal procurement contracts.
