4 / 5 page EPC 4 SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE © 2003 TELEDYNE RELAYS EPC\032003\Q1 Series EPC Firing delay time Analog input voltage 0V -> EPCXXXXXA 10V 8.4ms 4.2ms 0ms Load voltage 1 5 2 3 4 Firing delay time 10ms 5ms 0ms 20mA 1 3 Load voltage 5.5mA -> EPC24N40R 2 4 5 0mA Analog input voltage 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. 2. Full conduction mode voltage: Control Voltage = 10 Vdc (+0; –5%) 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. 4. Possible presetting zone by using the external phase angle adjust. 5. Firing delay angle limit: 170 ° (0; +5%); Conditions: EPC24 @ 135 Vac, EPC46 @ 240Vac INPUT/OUTPUT TRANSFER CHARACTERISTICS Figure 6a – EPCXXNXXA Figure 6b – EPC24N40R 1. Factory presetting to 170 ° ±10% (@50Hz)of the initial maximum firing delay angle. It can be modified by using the external phase angle adjust. A variation in load voltage causes a small decrease of this angle. For 60Hz see item 4. 2. Full conduction mode voltage: 20 mA (+0; –10%) 3. Factory presetting to 5.5 mA (+10%; –0) of the minimum control input current. 4. Possible presetting zone by using the external phase angle adjust. 5. Firing delay angle limit: 170 ° (0; +5%); Conditions: @135 Vac; Control input = 5.5 mA.
