JDL-100 (Control Voltage, 1.7m Cable + One EA CT) Hoist and Crane
LOAD LIMITER is designed to fully protect AC motor against conditions can cause damage.
It can protect the overload mechanical equipment such as Hoist & Crane.
If the motor is overloaded, phase over-current is monitored on the display,
alarm goes off and the relay energizes a contactor or breaker to cutoff the power automatically.
- ▶ Fine setting time and current are available by Microcomputer built-in it
- ▶ Running current to motor is displayed itself. Thus, setting current is easily
done without extra current meter.
- ▶ It is automatically reset if hoist or crane is descended during the reset time by
memorizing ascending time.
- ▶ Wiring and installing are very simple by using of external current transformer(CT).
- ▶ In case of being used for creep hoist,
the device displays each trip signal and current setting.
- ▶The device can be used as the over current relay for protecting AC motor.
