YSV7
Loads mentioned in this chart is for relays with no parallel diode or Zener Diode. For those with parallel diode, Zener Diode or other components.
please contact Hongfa for more technical supports.
Please also contact Hongfa if the actual application load is diffrent from what mentioned aboved.

Characteristic Curves
1. Coil operating voltage range
ysv7 z
There should be no contact load applied when maximum continuous operation voltage is applied on coil.
The operating voltage is connected with coil energized time and voltage After energized, the operating voltage will Increase.
The maximum allowable coil temperature is 180℃. For the coil temperature rise which is measured by resistance average value, we recommend the coil temperature should be below 170℃ under the different application ambient, different coil voltage and different load etc.
CHARACTERISTIC CURVES
2. Load limit curve
Load Limit
The contact load is resistive.
The load and electrical endurance tests are made according to “CONTACT DATA parameters table. If actual load voltage, current, or operate frequency is different from “CONTACT DATA table, please arrange corresponding tests for confirmation.
This chart takes 70A load as example.
3. Ambient temperature curve of the electrical durance test
