3.4.. Electrical.Specifications
On/Off.Outputs:
Max voltage= 240 Vac 50/60 HZ or 28 Vdc
Max motor load = 3/4 HP (13 FLA) @ 120 Vac, 2 HP
(12 FLA) @ 240 Vac
Max resistive load current = 15 A
Tungsten light bulb = max 5 A @ 120 Vac
Variable.Outputs:.
1/2HP @ 120 Vac, 1.5 HP @ 240 Vac
3.5.. Variable.Output.Wiring.
Some relay panels are provided with a built-in variable
output board which allows using 2 variable loads. If
your panel is equipped with this board, please read
the instructions below:
The same phases must be used to power up the
variable outputs & the relay panel on 3 phase
power.
Voltage.Selector
Set the voltage selector to the corresponding power
supply : 115 or 230 Vac.
Motor.Curve
Specify the motor curve that is being used by your
variable-speed fans. A table showing all possible
motor curves is available on the back of the instal-
lation guide leaflet included with your environment
control.
