Buffering with service free electrolytic capacitors 24V or 48V models available Constant output voltage in buffer mode Buffer time 0.2s at 20A (24V) or 0.1s at 20A (48V) Longer hold-up time at lower levels Buffer units can be connected in parallel to increase the output capacity or the hold-up time Easy to install, no need for control wiring. The buffer units can be added in parallel to the load circuit at any given point Clear status indication by status LED and signal outputs Quick connect spring clamp terminals
