787-1664 WAGO AC/DC Power Supplies

Wago 787-1664 is a 4-channel Electronic Circuit Breaker (ECB) module designed for protection unit applications. 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 selector switch, offering options of 2A, 3A, 4A, 6A, 8A, and 10A. Each of the four channels operates at a rated voltage of 24Vdc. The design includes a status message for each channel communicated via pulse sequence. The ambient air temperature for operation ranges from -25°C to +70°C, while for storage, it ranges from -25°C to +85°C. The module does not specify a supply voltage for AC, speed, control voltage for DC, or communication protocol but mentions an IP20 protection rating and a rated insulation voltage (Ui) of 45mm. It features a T 15A internal fuse per channel, 35Vdc reverse feed protection, and a suppressor diode (33V) for transient suppression on the primary side. The UPC code indicates compatibility with DIN-35 rail mounting, and the dimensions are H90mm x W45mm x D115.5mm. The module operates within a humidity range of 5-96% relative humidity (RH), with no condensation permissible.
