Electric Power Ec Motor With Ld250c-230d3-03 For Refirgeration
1. motor high efficiency range is big
2. the volume is very compact.
3. motor efficiency is high(>80%)
4. Motor efficiency loss is le
5. motor temperature rise is low
Over-current limiting circuit protects motor from damage at least for 72 hours
of locked rotor condition at rated voltage.
under Locked Rotor
A, Typical inrush current when the motor is trying to re-start under locked rotor conditions is 2~4 times the normal running current
reoccurring and for 16~20% of restarting cycle period.
B, If he CL function is used this restarting inrush current is about the same as
the normal running current.
|3-3||Reverse Polarity Protection||
No damage if the positive and negative leads are reversed under maximum
operation voltage conditions.
|3-4||Over Voltage Protection||
The circuit will be shut down automatically when input voltage over 60VDC.
And re-started when Voltage down to 60VDC below.
In 5 seconds after power on and speed control voltage gets to 1.5V or PWM
duty cycle at 10% above.
