Description

Titanium II 12V 5A Backup Power Supply & Battery Charger for 18Ah–20Ah AGM, Gel & LiFePO4 Batteries (ZTP1205B)

The Titanium II is a 12V backup power supply and battery charger designed for installations that require a higher-capacity standby power solution than the smaller Titanium I. Built for use with 18Ah to 20Ah AGM, Gel and LiFePO4 batteries, it combines smart charging with dependable backup power for security, communications and low-voltage systems.

With a 105W power rating, 5A max output current and 3A max charge current, the Titanium II is suited to applications where longer backup time or heavier 12V load support is needed. It includes a selectable battery type mode for lithium or AGM/Gel charging, helping match the charging profile to the connected battery.

The unit also features a low battery cut-off at 10.2V, a built-in AC fail relay, LED status indication and a buzzer alert to indicate mains failure and battery discharge state. All of this is housed in a lockable metal enclosure for a neat and secure installation.

Titanium II is suitable for a wide range of standby power applications including alarm panel backup, access control systems, CCTV backup, emergency lighting, battery charging, 12V router backup and other 12V devices. It is intended for indoor use only and should be installed by qualified personnel.
