FEATURES/BENEFITS
• Industry standard package
• Internal MOV (certain models)
• Control LED (certain models)
• AC or DC control available
• Excellent thermal performance
• Tight zero-cross window for low EMI
• High immunity to surges
DESCRIPTION
The Series ST single-phase relays are designed for
high-power applications. The design incorporates an
SCR or triac output. The Series ST relays utilize optical
isolation to protect the control from load transients.
Control LED is available on certain models. All Series
ST relays are zero crossing. Internal MOV is also
available on ST24D 25A and 50A models.
APPLICATIONS
• Heating control
• Industrial and process control
• On/Off controls of AC equipment
APPROVALS
All models are UL recognized.
UL File Number: E128555.
