Product features:
1. Range of application:
(H Type: AC100V-280V 50/60Hz, 10-28W 1A)
(L Type: AC/DC 12V-36V, AC/50Hz-60Hz, 10W-50W 2A)
(LA Type: AC37V-60V 50/60Hz, 10-28W 1A)
2. Power promote: 20%~300%(only for AC), especially for big capacity and high loading products.
3. Power save: 15%~85%, can decrease coil's temperature rise greatly.
4. High power start time: 0.3~2.5 seconds

5. Switch interval time: 0.7~5 seconds  
6. The covering makes from good quality engineering plastic which is flame retardant, high intensity and security.
7. Standard DIN43650A connector, protection class is IP65 if install correctly.
8. Ambient temperature: -25C~90C.
9. Field of use: Apply to drive of solenoid valves, especially for solenoid valves with high startup, high temperature rise and long time electrified. Be good for power saving, lowering temperature rise, and prolong life of solenoid valves.

Instructions:
You can use as long as connect to coil and connector.
H type: Input and output are nonpolarity.
L type: Input is nonpolarity. When output loading is AC, it is nonpolarity. When output loading is DC, pin 1 connects to negative pole and pin 2 connects to positive pole.
*Notes: Design according to specific products, unadjustable after delivery.
