Keystone MH-50X-Q-KIT-/A 50W Metal Halide Hid Ballast Kit

Product Description

The KEYSTONE MH-50X-Q-KIT-/A is a core-and-coil HID ballast kit engineered for 50-watt standard metal halide lamps. The kit ships complete with a dry-film capacitor, pre-wired igniter, mounting bracket, and all required hardware, making it a ready-to-install replacement assembly. Operating on a quad-tap, 4-tap voltage configuration, it accepts 120, 208, 240, or 277 volts, making it well suited for multi-voltage commercial and industrial lighting installations. The circuit type is HX-HPF (high-power-factor), and the ANSI code is M110. Licensed electricians and lighting maintenance technicians are the primary installers of this ballast type.

This ballast kit is intended for use in fixtures housing 50-watt standard metal halide lamps in commercial, industrial, and institutional lighting applications. Its quad-tap voltage range allows a single SKU to serve multiple panel configurations without requiring separate inventory. The HX-HPF circuit design provides high power factor correction, which is commonly required in commercial facilities to minimize reactive power load. The pre-wired igniter reduces field assembly time during replacement or new construction installs.

Key Features

• Complete kit includes dry-film capacitor, pre-wired igniter, mounting bracket, and hardware
• Quad 4-tap voltage rating: 120, 208, 240, and 277 volts for broad panel compatibility
• HX-HPF circuit type for high power factor correction
• Core-and-coil ballast construction with aluminum winding material
• ANSI code M110 for 50-watt standard metal halide lamps
• UL listed for Canada and the United States; RoHS compliant
• Minimum starting temperature of -30 degrees C for cold-environment installations

Compatibility

Designed as an OEM-style replacement ballast kit for 50-watt standard metal halide fixtures requiring an M110 ANSI-coded, HX-HPF circuit ballast on a quad 4-tap 120/208/240/277-volt supply.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) and all applicable local codes. Disconnect and lock out power to the fixture at the branch circuit breaker before removing the existing ballast or capacitor. Verify the supply voltage at the panel matches one of the four available taps before making connections. Allow the lamp and capacitor to fully discharge before handling any components.
