Power Save Device for Solenoid Valves

STC Model 2W200-C-P-S power save device can be used to
drive solenoid valves, especially for solenoid valves with high startup,
high temperature rise, and extended on time. It is useful in reducing
power consumption, lowering coil temperature, and extending the life of
the solenoid, increasing initial power which can speed operator cycle
rates and response time.

Normally closed solenoid valves require much less energy for
hold-in as opposed to pull-in. The STC Power Saver takes advantage
of this physical phenomenon. It boosts the power supply to the
solenoid valve for a short period of time to open the valve for a
short duration and then it reduces the power once the valve is opened.

Product Specifications and Features:

• Range of applications:
  • H Type: AC100V-280V 50/60Hz, 10-28W 1A, Input and output are no
    polarity.
  • L Type: AC/DC 12V-36V, AC/50Hz-60Hz, 10W-50W 2A. Input is no
    polarity. When output loading is AC, it is no polarity. When output
    loading is DC, pin 1 connects to negative pole and pin 2 connects to
    positive pole.
• Power Boost: 20%~300%(AC only), particularly useful for large capacity and high loading products.
• Power Saver: reduce power consumption 15%~85%, can decrease coil’s temperature rise greatly.
• High power start time: 0.3~2.5 seconds
• Switch interval time: 0.7~5 seconds
• Housing Material: flame retardant, quality engineering plastic
• Electrical Connection: Standard DIN43650A connector, protection class: IP65.
• Ambient temperature: -25°C~90°C.

CAUTION: Do not energize the solenoid coil when it is not
installed onto the valve. It may cause it to overheat and create a
fire hazard.
