Appendix

— Performance of 50VF Operators on 1Ø/3Ø, 50/60Hz Power

A HySecurity 50VF2, 50VF-EFO, or 50VF3 operator can operate on a wide variety of incoming power.



50Hz/60Hz operation with no changes or reconnection



1Ø or 3Ø operation by field reconnection.



The incoming voltage must match the operator nameplate. Although the electric motor can be reconnected, a

different VFD (motor controller inside the grey control box) is required between 460V and 208V/230V.



Any AC powered peripherals such as locks, card readers and other devices need to be checked for compatibility.



The electric motors in all VF2 and VF3 operators are 3Ø/60Hz motors and are connected for the voltage on the

operator nameplate. (208V/230V or 460V)

How is this done?



The VF controller in the operator is rated to operate on input frequencies ranging from 48Hz through 62Hz on 1Ø

or 3Ø power (a jumper connection is required for phase change) but only on either 460VAC or 208V/230V. (A
change between 460V and 230V, either direction, requires replacing the VF controller).



The control transformer in the operator is tapped for multiple voltages and rated for 50/60Hz operation.



The VF controller first rectifies and filters the incoming power to DC, which has no frequency or phase. It then

creates 3Ø variable voltage/variable frequency AC for the motor from the DC.



Depending on the model, the VF controller ramps the motor voltage and frequency from 0V@0Hz at start, to

either 208/230 or 480 VAC @ 60Hz for full speed. This allows use of 60Hz motors regardless of the incoming
frequency.

Since the input voltage/frequency is converted to DC to begin with, there is absolutely no relationship between the input
frequency/phase and frequency/phase of the power supplied to the motor. The input could be 1Ø or 3Ø, 48Hz or 62Hz
and the controller/motor combination wouldn’t care. It will create the ramped 3Ø voltage and frequency for which it is
programmed.

NOTE:

50VF operators connected for 1Ø operation will draw more current from the utility than those connected for 3Ø

(approximately double); because the utility power to run the machine will be carried to the operator on two wires instead of
three. Be sure to allow for this difference when specifying wire size.

In-Field Connections

50VF-series operators are field re-connectable for 1Ø or 3Ø input power without changing the VFD Controller.

WARNING: 50VF-series operators CANNOT be connected to 120V, 1Ø power or 575V, 3Ø power. If any attempts
are made to do so, serious injury, electrical shock, or death may result. Any electrical damage occurring to the
operator will not be covered by the Limited Warranty.

WARNING: 50VF-series operators are NOT field reconfigurable between 208/230VAC and 480VAC power. The VFD
Motor Controller in a 208/230VAC unit must be replaced with a VFD Motor Controller manufactured for the higher
(480VAC) voltage input.
