## Questions & Answers

**Q: What is the maximum frequency this can be turned on and off?**
A: This is mainly in reply to the incorrect info provided by another person.  The stated on/off is 10ms, therefore it takes 10ms to turn on and another 10ms to turn off, totaling 20ms, or 0.020 seconds.  Take the reciprocal of 0.02 which is 50 (Hz), and that's the maximum frequency, as stated by the seller.  HTH.

**Q: Do you need fan cooling or can you use just a heatsink?**
A: Dear customer：A heatsink must be installed for the 100DD. If the working time and current are not large, the fan does not have to be installed. If the time is long and the current is large, a fan must be installed.

**Q: What is the activation current in milliamperes for these? Does it change from the 25a to 100a?**
A: Dear customer：For DD type solid state relays.Control voltage is 3-32VDC, activation current is 5-25mA.
The greater the voltage, the greater the current, and the maximum will not exceed 25MA.

**Q: Can i use the ssr-150d x 600vdc to switch 325vdc of pv between two equipment (grid-tie 3kw and water pump 2.2kw)?**
A: Sorry.pump is inductive load. can not use ssr.
