(Pfinztal, October 2023) CAMTEC POWER SUPPLIES, the German acknowledged specialist for particularly robust capacitive loads and laboratory power supplies, is expanding its successful portfolio of AC inrush current limiters: The new CAMTEC ESB001 series is available worldwide as of now. The 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 in just the dimension of a single-phase circuit breaker. The series‘ name ESB stands for „EinschaltStromBegrenzer“ – the German term for this type of device.
The reason for the vast worldwide growth of demand for CAMTEC Power Supplies‘ inrush current limiters in safety-relevant grids throughout the last decade is easy to understand: In a grid using inrush current limiters, the sum of all inrush currents in the sub-distribution net are kept extremely low. This makes the net stable and fail-save. Besides: Not having to switch-on the different network areas sequentially and being able to use simpler components in the electric system nevertheless, saves up to ten percent of the total costs, when planning light, tunnel or industrial electrical installations.
Due to the low heat production of only 1.1 W @230Vac at 99.97 % efficiency, the new ESB001 components can be mounted wall-to-wall with neighbouring devices in the control cabinet. Therefor the new ESB001 units are the perfect solution wherever space in the switch cabinet is very scarce – like in LED-retrofits in buildings or street lighting. The new, tiny design also makes them suitable for displays in shop solutions, display cases at airports or in city centres.
Beyond this, the CAMTEC ESB001 retains all the features and benefits of the inital ESB101 and ESB303 series, as well developed, designed and produced by CAMTEC Power Supplies in the Black Forest: Those are being used for more than a decade yet, wherever particularly reliable protection of lighting and machinery applications is required.
The global distributors will be supplying two versions of the new ESB001-series: The ESB001.LED.230VAC is perfectly supporting LED lighting networks in buildings, street lighting and tunnel lighting. The ESB001.24.230VAC is suitable for protecting against contact fires on load relays or protecting multiplexed MUX channels from damaging inrush currents in industrial surroundings.
The ESB001 meets the demanding industrial standards EN61010-1, EN61010-2-201 as well as the current IT standard EN62368-1. They are totally EMC-neutral and can – alike the CAMTEC ESB101 and ESB303 limiters – be used in all frequencies from the 16 2/3 Hz railway networks to 400Hz on-board networks.
