STEP capacity module, with maintenance-free energy storage based on double-layer capacitor, DIN rail mounting, input: 24 V DC, output: 24 V DC / 2 A / 0.4 kJ
The compact STEP DC UPS with integrated capacitor can bridge power failures lasting up to one minute. The space-saving capacity module combines an electronic switch-over unit and energy storage in the same housing. The capacity module stores the energy required to bridge mains failures in maintenance-free double-layer capacitors. This ensures high system availability.
