high voltage reed relay

  • The photo shows as some H.V Reed Relays (Model : KT-1A24-15K) are installed in a PCB.
    KAST offers the PCB when customer buys the Reed Relay.
    And where on the PCB there are terminals to connect wires, so the user can install 2, 4, 6, or 10 relays easily. 
  • Price : 42 (USD) per unit (Included install PCB)

Explanation of KAST's H.V Reed Relays
  1. Only KAST manufactures the H.V Reed Relays in Korea.
  2. The vacuum glass contact inside is made in USA, France, or German, it means the quality of the H.V Reed Relays is trust worthy.
  3. KAST has the patent on H.V Reed Relay. 
  4. There is an LED lamp which display the statement of the H.V Reed Relays if it is On(Make), or Off(Break) position. 
  5. The vacuum glass is installed inside of the mold case, so it is strong against the phisical shock or vibration. 
  6. Each of all H.V Reed Relays get the Serial No. after strick test, then delivered to the customer.

 

The final finished H.V Reed Relays have the Serial No.
The photo shows 2 Reed Relays installed in the PCB.
KAST offers the suitable PCB free when the Relays delivered.

An example these H.V Reed Relays are used

Photo shows an example that the H.V Reed Relays are used in H.V On / Off control in a controller with automatic test system.

Manu H.V Reed Relays are installed in a controller where they are are turn On and Off the H.V lines.
H.V Reed Relays are not only used in H.V On / Off line but the contact resistance is required as very low and good repetitive
