24VDC Uniterruptible Power Source

A continuous, reliable power supply is vital to protecting instrumentation and programmable logic controllers (PLCs) from electrical power failure and avoiding costly downtime. To support and protect these critical systems, McClure Energy Solutions has designed a DC uninterruptible power source (UPS) with a reliable, stable power system. Designed using off-the-shelf components, the UPS uses 120VAC input power and provides an uninterruptible 24 VDC output power (12VDC optional).

Our UPS provides dry alarm contacts to alert your process controller when the status changes to a power failure or if the batteries have started to fail, so the necessary action can be taken prior to power loss. Designed for longevity and durability, the UPS incorporates a microprocessor-based smart battery charger to provide optimal battery charging patterns and desulphation when needed. This result is no battery over or undercharging, which increases battery life.
