EPSITRON Capacitive Buffer Modules

Brief power supply failures jeopardize the trouble-free operation of machines/systems. The power supply buffer times of particular applications can be considerably extended via capacitive buffer modules. These modules have power reserves that may be required when starting heavy loads or triggering a fuse. The 787-880 and 787-881 Buffer Modules contain "gold caps" to store energy and are therefore absolutely maintenance-free, providing output power for 400ms. Buffer times up to several seconds can be easily achieved by connecting the modules in parallel or adjusting the output current.

Decoupled output

Multiple buffer modules can easily be connected in parallel. The module outputs are decoupled from the inputs. This means that it is possible to specifically buffer just selected consumers.

Signaling

1. Via LEDs: There are 3 LEDs to signal individual operating conditions. The green LED indicates error-free operation. The red LED indicates undervoltage at the buffered module output. The yellow LED lights up when the module is charging.

2. Via isolated signal contact: Once the internal charging procedure is complete and there is sufficient voltage at the buffer module input, the isolated signal output is activated. The contact is deactivated as soon as the module runs out of charge and the control level can respond to this change of state.
