FEATURES/BENEFITS
• External phase angle adjust
• Designed for all loads
• Excellent thermal performance
• Internal output protection
• Proportional control with voltage or current input.
DESCRIPTION
The Series EPC phase angle controller has an analog
input isolated from the mains to vary the phase angle
proportionally to the input and load voltage. The EPC
phase angle controller is designed mainly for resistive
loads. The EPC may be used with inductive loads,
but with limitations. It provides internal protection from
load transients. The conduction level is controlled by
the input. The Series EPC provides an external adjust
that allows the user to modify the cycle time for any
particular application.

1. Factory presetting to 144° ±10% (@50Hz)of the initial
maximum firing delay angle. It can be modified by using the
external phase angle adjust. A variation in the load voltage
causes a small decrease of this angle. For 60Hz see item 4.
1. Factory presetting to 170° ±10% (@50Hz)of the initial
maximum firing delay angle. It can be modified by using the

2. Full conduction mode voltage: Control Voltage = 10 Vdc
(+0; –5%)
2. Full conduction mode voltage: 20 mA (+0; –10%)
3. Factory presetting to 0.2 Vdc ±0.1V of the minimum control
input voltage. Below 0.2Vdc, the relay is off; above 0.2Vdc, the
relay is On at a firing delay angle that depends on the external
phase angle adjust.
