SP 1250DLE

Clean power for the next generation

SP 1250DLE Overview

Our newest digital UPS is designed for ITS and traffic applications, including the new low-voltage ATC cabinets. It’s the only double conversion, true on-line UPS with both AC and DC power inputs and outputs, and it comes in a compact 1U rack-mounted package. The SP 1250DLE is designed for temperature extremes of ‑40°C to +74°C (-40°F to +165°F) and supports 85-155 VAC or 48 VDC input voltages, as well as generator input. The unit provides a 120 VAC output and 48 VDC, 24 VDC, and 12 VDC outputs, up to an 875 watt maximum for all outputs combined. For customers who do not yet require DC support but anticipate a future need, the SP 1250DLE can be ordered without DC output and later upgraded in the field.
