Pass & Seymour BZ250 Wattstopper 24 VDC Universal Voltage Power Pack

Pass & Seymour BZ250 Wattstopper 24 VDC Universal Voltage Power Pack

The Pass & Seymour BZ250 is a Wattstopper 24 VDC universal voltage power pack designed to control lighting or plug loads with either auto-on or manual-on operation for code compliance. Built around a mechanically held latching relay, the BZ250 offers selectable power-loss behavior and a plenum-rated switching power supply for reliable operation in commercial and industrial lighting control systems. A built-in Load On/Off button lets installers verify wiring at the panel without additional test equipment, and Hold-On/Hold-Off inputs allow integration with occupancy sensors and other low-voltage control devices.

Key Features

• Load Verification: Integrated Load On/Off button lets installers verify wiring directly at the power pack.
• Mechanically Held Latching Relay: Selectable power-loss operation - On, Off, or last state - for predictable behavior during outages.
• Auto-On or Manual-On Operation: Configurable switching modes support local energy-code compliance requirements.
• Zero-Crossing Switching: Reduces relay contact wear for improved reliability and increased product life.
• High-Efficiency Power Supply: Plenum-rated switching power supply suitable for installation in air-handling spaces.
• Hold-On and Hold-Off Inputs: Enables coordination with occupancy sensors and other lighting control inputs.
• Low Voltage Overcurrent Protection: Built-in protection helps safeguard the control circuit and connected devices.
• 24 VDC Universal Voltage: Rated for both lighting and plug load control applications.
