FEATURES/BENEFITS
• Industry standard package
• Internal snubber (except S60 models)
• Designed for all types of loads
• AC or DC control available
• Excellent thermal performance
• Tight zero-cross window for low EMI
• High immunity to surges
DESCRIPTION
The Series S single-phase relays are designed for
all types of loads. The design incorporates an SCR
or triac output. The relays utilize optical isolation to
protect the control from load transients. All contain an
internal snubber for output protection. High-current
models are excellent for motor and phase angle
control.
APPLICATIONS
• Heating control
• Motor control
• Uninterruptible power supplies
• Light dimmers
• Industrial and process control
• On/Off controls of AC equipment
APPROVALS
S24 and S48 models are UL recognized.
UL File Number: E128555.
