General Description:
The CAMTEC ESB101-series are the 2nd generation and cost effective inrush current limiters. The limiters are made for
115/230Vac 16A networks. The line frequency range is 16⅓Hz – 440Hz. The ESB101-Limiter shall be located between the
line-switcher/contactor and the load (p.2/Fig.1). The ESB-models are designed for inductive and capacitive loads. In the
moment of switching-on the system the inrush current of the installed load will be limited for the defined time T
on
(p.4/Fig.5). Independent from the previous inrush level; the current limiting is always strict. After T
on
elapses the current
limiting circuit of the ESB101 will be bypassed. Then the load is directly connected to the AC. The electrical network can
be stressed with current loads as normal (e.g. motors, pumps). If an AC dump overshoots the defined time T
off
, it will be
detected by the ESB101 (p.4/Fig.6). As soon as the AC recovers the inrush will be limited, again (p.2/Fig.3 & 4). The
ESB101-models provide an internal temperature control. In case of a failure the device shuts down to safely prevent
from overheating or burning.
