240V battery replacement for high-capacity Symphony systems

The Uniti Power URBK3 is a replacement battery kit for the Symphony EBM2409RT3U 240V external battery module. One URBK3 kit replaces the batteries in one EBM2409RT3U, the 3U module used to extend runtime on the Symphony 6kVA and 10kVA online UPS. URBK3 uses maintenance-free VRLA batteries and has a 2-year repair-or-replace warranty.

On larger Symphony systems, battery strings are an integral part of the overall UPS design, and runtime falls as batteries age even while the UPS electronics stay serviceable. Fitting the specified URBK3 kit at the point where capacity is reducing helps maintain the correct battery voltage, charging characteristics and physical fit for the platform, so the system continues to deliver the runtime it was specified for.

Compatibility

• EBM2409RT3U external battery module: one URBK3 kit per module.
• Symphony 6kVA and 10kVA UPS battery modules: Uniti Power also describes URBK3 for the battery modules of compatible SPY6KiRTB and SPY10KiRTB systems, each of which is supplied with a 3U battery module.

For the battery module supplied with a SPY6KiRTB or SPY10KiRTB, or for any other unit, confirm the kit and quantity with Uniti Power technical support before ordering.
