UOA-0266 Under Voltage Monitor/Relay

The UOA-0266 is a compact, reliable solution for detecting phase sequence errors and loss conditions in three-phase systems. Designed with a solid-state voltage sensor and a high-accuracy DPDT relay, this monitor helps ensure proper equipment operation and protection by identifying out-of-sequence or low-voltage conditions before damage occurs.

Features:

• Solid-state voltage sensing with mechanical relay output
• Adjustable drop-out range: 80–120 VAC
• Factory preset trip point: 108 VAC (drop-out), pick-up 1–3% higher
• DPDT output rated 10A resistive / 211 VA inductive @ 120 VAC
• Fast, reliable response times:
• Operate delay: 0.1 seconds
• Release delay: 0.5 seconds
• Wide operating temperature range: 40°F to 160°F
• Durable surface-mount enclosure (Style “E”) with orange Lexan housing
• (12) #8-32 screw terminals for secure field wiring

Applications:

• Motor control panels
• HVAC systems
• Industrial automation
• Pump protection systems
• Electrical distribution panels
