The IQT3 Pro Battery Backup actuator provides valve fail-safe operation by utilising power from a battery source during AC supply mains failure. Under normal supply conditions the actuator operates from the site AC electrical supply. On loss of this supply the actuator automatically switches over to receive power from a 24 VDC supply allowing control of the valve to the pre-configured position. IQT3 Pro Battery Backup Type 1 — External Supply Suitable for use in hazardous and nonhazardous locations, Type 1 includes connection for a customer supplied 24 VDC supply in addition to the normal AC supply. IQT3 Pro Fail-safe Type 2 — Integral Battery Suitable for use in non-hazardous locations only, Type 2 includes a battery located in the actuator terminal cover, charged from an integral charging system when AC power is applied to the actuator. IQT3 Pro Battery Backup offers the following powerful features: Same performance as Standard IQT3 Pro 3-phase, 1-phase and DC power supplies (Type 1 only) Modulating duty option Full-turn and multiport option Compatibility with all networks
