Existing reviews of 50A High Voltage DC Contactor, 12V/24V coil
Does your 50A high voltage DC contactor have a gas or vacuum filled arc chamber?
I want to ask if your 50A high voltage DC contactor ADH150/900-E has a gas or vacuum filled arc chamber?

Our ADH series of DC contactors have inert gas in the arc chamber.
1. Why does the DC version cost 20$ more? Is there a difference in the internal structure between AC coil and DC coil?
2. What are the typical open/close times?
3. The supported altitude is 2000m. Is there an option to increase it to 2500m?

1. The DC coil version is larger, and the material is different, so the price will be higher.
2. The reaction time of contactor "typical open/close" is 0.3 second.
3. Yes, it can be used at an altitude of 2500m, but this may have a little impact on performance.
