Datasheet

Accepting AC inputs from 90 to 265VAC, the ESB-101 series peak inrush current limiter designed for inductive and capacitive loads has been unveiled by Powersolve. The low cost devices are more than a simple NTC solution: the series limits power-up currents and provides continuous operation up to 16A.

The ESB-101 is a true current limiter and cuts off all peak currents when starting loads under practically every AC condition. Designed to provide high reliability and maintenance-free operation, it is fitted with an internal temperature fuse to prevent overheating should the bypass circuit fail.

Peter Clark, Managing Director, Powersolve, commented: "Extreme conditions can occur on AC lines in the event of a break in the supply. When power returns, high current peaks will trip circuit breakers and, in decentralised areas for example, this will often lead to increased maintenance costs as the breakers require re-setting. The ESB-101 prevents this happening."

The ESB- 101 has an inrush limiting time as low as 300ms, a capacitance range of 1500 to 4000µF and an operating temperature range from -40 to +70°C, It can be wall or DIN Rail mounted, accepts 26 to 10AWG wire with spring terminals and comes in an IP20 rated housing. The series is suited for use in LED lighting and other applications using multiple switch mode power supplies, where short mains interruptions and start ups can cause very high peak inrush currents.
