OP8111 User Manual
INTRODUCTION
Powering up
INTRODUCTION
The OP8111 high voltage amplifier is transformer based and designed for use with an OPAL-RT
simulator or as a standalone amplifier. It provides up to 3 isolated high voltages up to ±160Vrms / 50VA
(maximum) and the maximum input voltage range is ±10V_max before output clamping.
Outputs can be configured in Wye or Delta.
The amplifier is designed with connections for one to three phases, depending on the configuration
requested. Each phase is equipped with two connectors, and four status LEDs.
Typical use cases are motor and power grid emulation.
STARTUP PROCEDURE
POWERING UP
The unit has two power switches, for ease of use. Follow these steps to properly power up the OP8111
Power Amplifier:
1. Press the switch at the rear of the unit to put it in the ON position
2. Press the switch at the front of the unit to put it in the ON position. Both Power Good and AC/ON
LEDs must be on.
3. Verify Status
The OP8111 voltage amplifier is equipped with a series of LED indicators that display the phase
status:

Once the front power switch is in the ON position, fans will initially run at maximum speed before
returning to a slower, nominal speed.
Each phase has 4 LEDs to indicate its status:
