787-1664/006-1000 WAGO AC/DC Power Supplies

Wago 787-1664/006-1000 is a protection unit designed as a 4-channel Electronic Circuit Breaker (ECB) module. It features reactivation of all tripped channels via a 15-30Vdc pulse for a minimum of 500ms and allows for the switching ON/OFF of any number of channels via a pulse sequence. The supply voltage requirement is 18-30Vdc with a nominal 24Vdc, and it utilizes push-in CAGE-CLAMP spring connections for connectivity. The rated current is adjustable for each channel via a selector switch, offering settings of 0.5A, 1A, 2A, 3A, 4A, and 6A. Each of the four channels operates at a rated voltage of 24Vdc. The design includes active current limitation and provides a status message for each channel via a pulse sequence. The unit does not specify a supply voltage for AC and operates within an ambient air temperature range for operation of -25°C to +70°C and for storage from -25°C to +85°C. The degree of protection is IP20, and the control voltage for DC is specified with a T 15A internal fuse per channel, active current limitation at 1.7 x Io nom (typ.), 35Vdc reverse feed protection, and a suppressor diode (33V) for transient suppression on the primary side. The unit's dimensions are H90mm x W45mm x D115.5mm, and it is designed to be mounted on a DIN-35 rail. It can accommodate 5-96% relative humidity (RH) without condensation.
