PS ESB001 Inrush Current Limiter

October 21, 2023

The CAMTEC Power Supplies’ ESB001 inrush-current limiter series is by far world’s smallest of its performance class. It requires just 1 TE (17.5mm) space on the top-hat rail, which commonly is only the dimension of a single-phase circuit breaker.

The ESB001 series is developed and produced by CAMTEC Power Supplies GmbH in Germany. The acknowledged specialists for particularly robust capacitive loads and laboratory power supplies are releasing the new series in two versions: The ESB001.LED.230VAC aims at traditional LED lighting in buildings, street lighting and tunnel lighting. The ESB001.24.230VAC is suitable for protecting contact fires on load relays or protecting multiplexed MUX channels from damaging inrush currents.

Due to the low heat production of only 1.1 W @230Vac at 99.97 % efficiency, the ESB001 can be mounted wall-to-wall with neighboring devices in the control cabinet. Therefor the ESB001 units show their strength wherever space in the control cabinet is very tight – like in retrofits in buildings or in street lighting. The small design also makes them suitable for displays in shop solutions, display cases at airports or in city centers. In particular, the model ESB001.24.230VAC helps to keep the sum of all inrush currents in the sub-distribution extremely low, so that costs will be saved for not having to switch on the different network areas sequentially.
