Single Output to 125A 660 Vac
AC/DC Control
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.
