The PJU models will switch to battery operation (batteries not included) without interruption to prevent end-product downtime for the customer in the event of power disruption or unexpected loss of AC input power. Consequently, the PJU series can increase the operational reliability of a critical operation. Convection cooling is applied for the single phase design with wide operating temperature range from -20C to +70C. The diagnostic monitoring signals for AC OK and Battery Low status will alert the user of any failure through TTL open collector. Metal chassis with case cover is available as option for different installation preferences.
