KSD301 series thermostat work principle:
KSD301 series products are a kind of metal with double as temperature component of the thermostat, electric equipment to work normally, optic-fiber in free state, contacts in a closed/disconnect state, when the temperature reaches action temperature, optic-fiber heated produce internal stress and rapid movement, open/close contacts, cut off/connect circuits, thus playing a role of temperature control. When electric cooling to reset temperature, contacts to be automatic closed/open, restore normal condition.
KSD301 serial thermostat parameters:
(1) the electrical parameters: 1) CQC, VDE, UL, cUL AC250V 50 ~ 60 Hz 5 A / 10 A / 15 years (resistance sex load)
UL AC125V frequency 50 Hz 15 years (resistance sex load)
(2) the action temperature range: 0-300 c(optional), temperature precision: ± 2 ± 3 ± 5 ± 10 c
(3) reply and action temperature difference: 8 ~ 100c (optional)
(4) the wiring way: It is terminal 250 # (curved 0 ~ 90 ° Optional); In terminal 187 # (curved 0 ~ 90 ° Optional, 0.5, 0.8 mm thickness optional)
A headscarf use life: 100000 times frequency
Electrical strength: AC frequency 50 Hz 1800 V lasted 1 min, no flash, no breakdown
[contact resistance: More than 50 m
Stuff insulation resistance: 100 M frequency
Contact form: Closed type: Temperature rise, contacts disconnect, temperature drops, contacts through;
Often open type: Temperatures rise through contacts, temperature drops, contacts disconnect
Shell protection level: IP00
Installation: KSD301 series installed ordinary activities ring, install small round activity ring, installation flat activities ring, with mounting holes ordinary large aluminum cover, with mounting holes extended aluminum cover.
KSD301series thermostat control method:
1. Auto reset: Following the temperature rise or down. The contactor auto close or open!
2. Manual reset: When the temperature rise, contactor auto open, when the temperature down, make the contactor close by hand!
3. Once work:
4. Auto and manual together:
KSD301 series compete advantage:
(1) stable performance
(2) high precision
(3) small, light weight
(4) high reliability, long life circle
