Frequently Asked Questions
What does CP43B-21 mean in VFD300CP43B-21?
CP is the CP2000 series, 43 means a 380 to 480 V three-phase supply, B is the hardware version, and the 21 suffix means IP20 enclosure with NEMA 1 / UL Type 1 wall mounting.
Is VFD300CP43B-21 a variable torque or constant torque drive?
The CP2000 is dual rated. The 30 kW in the model number is the light duty (variable torque) rating for fans and pumps. On a constant torque load it is rated 22 kW.
Does VFD300CP43B-21 support multi-pump control?
Yes. The CP2000 includes built-in PID with sleep and wake functions, multi-pump and multi-motor control, flying start and fire mode, which is why it is the usual choice for HVAC and water systems.
What is the difference between CP2000 and C2000?
CP2000 is optimised for fans and pumps, with BACnet built in and HVAC functions. C2000 is the heavy duty vector drive for cranes, extruders, winders and closed loop applications.
