OC2B is an open/closed chassis motor control that has been designed as building block solid state regulated power unit. OC2B uses state of the art control circuitry which can be used by itself, by wiring in the provided speed potentiometer as a straightforward speed regulated control or can be incorporated into much more sophisticated system designs contactor operation, external speed programming and tach feedback etc.

Control Method:
Sine-wavepulse width modulation(PWM) control

Output Frequency Range:
0.5 - 360 Hz
To operate the beyond 50/60 Hz,
consult the motor manufacturer
about the maximum allowable speed

Frequency Accuracy:
Digital command:

Analog command:
+ 0.2% (25°C + 10°C) of the max. frequency

Frequency Setting Resolution:
Digital: 0.1 Hz

Analog: Max. frequency/1000

Volt./Freq. Characteristics:

Overload Current Rating:
150%, 60 Seconds

Acceleration/Deceleration Time:
0.1 ~ 3000 sec. (linear/curve, accel./decel.),
Second stage accel./decel. setting available

Braking:
Dynamic Braking (short time)-
Approx. 100%: up to 1 HP
Approx. 70%: >1 HP & < 3 HP
Approx. 20%: > 3 HP
The braking torque at capacitive feedback is the average deceleration torque at the shortest deceleration (stoppage from 50/60 Hz) of the motor itself. It is not the continuous regenerative braking torque. And the average deceleration torque varies with motor loss. This value decreases when operating beyond 50/60 Hz. If a large regeneration torque is required, the optional braking resistor should be used.

DC Braking -
Operating frequency, time and braking force variable.
