FEATURES
The RRU provides an interface between a line voltage normal power sense
circuit and the low voltage remote override input on Synergy SYPM power
modules. All connected SYPM modules will be overridden to full ON if normal
power falls below 90% of nominal voltage.
• Works in conjunction with Synergy SYPM power modules
• One RRU is needed for each Synergy cabinet to be overridden
• Available to sense either 120VAC or 277VAC normal power
• 90% nominal input voltage drop out
• SPDT low voltage dry contact outputs rated for 10 Amps
