Description
1750mA Constant Current LED Driver for 277-480V Circuits with 1-10V Dimming
The KHM Kerham MSPI-HDIM70W12S-1750 is a dimmable constant current LED driver that delivers 1750mA across a 30-38V DC output range from a 277-480V AC input. For replacement, match the fixture LED current, operating voltage, dimming method, and mounting space of the original driver.

Benefits
The 277-480V AC input supports 277V, 347V, and 480V commercial and industrial lighting circuits. Active power factor correction and surge protection help the driver hold up on high-voltage installations.
Applications
Use as a replacement driver in high-voltage integrated LED fixtures, such as area, wall pack, and high bay lights, whose modules require 1750mA constant current within 30-38V DC.
Frequently Asked Questions
Will the MSPI-HDIM70W12S-1750 work on a 480V circuit?
Yes. The driver accepts 277-480V AC input. It is not intended for 120V circuits.
What dimming does the MSPI-HDIM70W12S-1750 support?
The driver supports 1-10V DC dimming and includes a separate 12V auxiliary output for compatible fixture controls.
