- WAGOs Capacitive Buffer Module bridges short duration voltage drops or load fluctuations.
- For uninterrupted power supply
- Internal diode between input and output enables operation with decoupled output.
- Buffer modules can be readily parallel-connected to increase buffer time or load current.
- Potential-free contact for charge condition monitoring
The WAGO 787 series capacitive buffer module provides a 24Vdc output at 20A, with an input voltage range of 20-30Vdc. It features CAGE CLAMP spring connections and is designed for DIN-35 rail mounting with a width of 57mm. The module is rated IP20 and operates in ambient temperatures from -10°C to +50°C, equivalent to model 787881.
