The Command Access PS2BB power supply boards are now available to field retrofit the discontinued Von Duprin PS873-2 power supplies. These boards are high quality, cost effective solutions for powering up to two electric latch pullback exit devices. Each power supply provides the necessary surge current to fire Von Duprin, Dor-O-Matic, and Command Access latch pullback devices. Additionally, each model includes a Fire Alarm link and the PS2BB-BO includes a battery charging circuit. These power supply boards offer features found on much more expensive power supplies all with solid-state design. The features, design and careful attention to detail make the PS2BB boards the ideal retrofit choice for the discerning user who requires a power supply that can offer years of trouble-free operation.
