The CX4000B controller is a PCB level controller powered by DC source that delivers a custom power waveform to the inductive shutterload. This controller can provide high-speed, high-power custom waveforms suitable for even our most demanding shutters. Key features include motion dampening via 5 parameters of magnetic force management, reverse polarity (hot swap) on power terminals,control signal noise isolation. RoHS (lead free) Compliant.

Intended Use: Where switching performance is critical, especially on larger aperture shutters, providing performance difficult to achieved on user-built circuits. Controller can drive all safety/process shutters and all modulation shutters.
Calibration: Unit is factory programmed via microcontroller and/or trim pots for use with each corresponding shutter model, and in the case of large optic shutters, calibrated additionally for gravity orientation effects. Label on product denotes mating shutter model.
Shutter Compatibility: Nearly all our shutters can be driven with the CX4000B.In higher performance shutters, the ultimate performance, switching speeds, and repetition ratesare typicallyachievablewith the CX4000B through careful calibration.
OEM Integration Considerations:
Electrical Safety: The 24 VDC standard power input makes for simple electrical safety certification in integrated systems.
Control Signal & Connections: The input control signal can be TTL or up to 12 VDC. Positive polarity opens the shutter. Polarity markings are shown on mechanical drawing and PCB silkscreen labeling.
Output Power and Connections: The controller outputs an inductive load waveform optimized to each shutter model. In general, 24 V is applied to the load for short timed period, then the controller will use PWM to lower the voltage to a long-term hold level. The inductor is not part of the switching circuit, only an inductive load.
Power–Up Considerations: The user’s power supply should be able to surge current into the CX4000B surge capacitor on initial power up. In operation, the surge current needed to drive the shutter load comes from the capacitor. If the available power supply is of minimal current rating, a soft start buffer (current ramp) should be considered.
Connections and Operational Procedure: See mechanical drawing for mounting hole location and spacing, and connection polarities.
