Inrush Current Limiter, Inrush Protector, 3-phase 200/400/500Vac For inductive & capacitive loads, 16A/32A -40°C...+70°C Short Specification:  Peak- / RMS Value Limiter  Integrated Phase Control Circuit  200/400/500Vac 3PH 16A/32A nominal Voltage  DIN TS35mm Rail  Federzugklemmen 0,5...16mm²  Integrated Bypass-Relay  Capacitive Load 2.000uF  Built-In Temperature Control Circuit  IP20 Housing The ESB is a budget-priced inrush peak current limiter for high loads in LEDapplications, complex automation systems and in the machine building. The ESB offers high recommended and interference free operation with both, the inductive and the capacitive load. It is simple to integrate into existing equipment. The ESB is selfpowering and does not require an external power supply. Integrated Phase Controller No simple NTC-Version! A Camtec-ESB allows effective reduction of cabling cross sections. It allows using quicker circuit breakers. The ESB prevents from tripping the circuit breakers by high inrush.

delay control Phase detector Phase failure Power Input Field Applications: The ESB limiter allows connecting much more loads (e.g. LED-power supply / LED-driver) to a pre-installed circuit breaker CB. The ESB definitely avoids that the CB can be tripped. This occurs independently from the objective initial current. The result is that the number of A.C. branch lines and the pre-installed CB can be reduced dramatically. Installation cost exhibit a sustained decline. Alternatively the cross section of the branch lines can be reduced when using smaller and faster responding circuit breakers....

The signals "Phase-Error" and "Asymmetry-Error" can be used to trigger an external contactor. The installed load will be disconnected if an error occurs. As soon as the error recovers the installed load will be reconnected to the AC. (find attached pictures „Phase-Loss &-sequence“ and „Asymmetry, Over-/Low Voltage“. The contactor is always named K2.) Phase Loss & Sequence In case of phase loss relay 4 opens after a delay time of 30ms. Synchronistic the relay of the appropriate phase opens, too and its green LED extinguishes. When the phase sequence is incorrect, relay 4 opens after a delay...

The Ton-time (limiting period) and the Toff-time (response time to arm the circuit after a phase lost or voltage drop) can be adjusted by the owner. The factory settings are Ton=150ms and Toff=100ms. Note: the adjusting range is non-linear. Safety Tests: Test Type and Factory Tests are executed by the manufacturer. Do not repeat the tests in the field. To arrange the field test remain to the following rules: a) Use approriate test equipment which apply the voltage with a slow ramp b) For every Test L1, L2, L3 at the input and at the output must be connected, Earth must be connected c)...
