FEATURES/BENEFITS
• Designed for all types of loads
• Dual output (two relays in one package)
• Faston terminals
• Connector for common or individual control
• Tight zero-cross window for low EMI
• High immunity to surges
DESCRIPTION
The Series SD dual-phase relays are designed for all
types of loads. The design incorporates two relays in a
single package. The relays utilize optical isolation to
protect the control from load transients. High-current
models are excellent for motor and phase angle control.
The 50A 600 Vac models are available with common
control connector or individual control connector.
APPLICATIONS
• Motor control
• Heating control
• Uninterruptible power supplies
• Light dimmers
• Industrial and process control
• On/Off controls of AC equipment
APPROVALS
All models are UL recognized.
UL File Number: E128555.
