Introduction

megasaver

Devtech Megasaver (DMS) is an electronics ballast for High Intensity Discharge lamps (HPS/MH/CMH/CDM-T). It is retrofit one box solution which gives constant output.

Features

Protection Feature

  • Built-in 6kV/3kA Surge protection.
  • Lamp over voltage protection & shutdown.
  • Lamp under voltage protection & shutdown
  • Lamp short circuit/Warm-up failure protection & shutdown.
  • Open circuit/No-lamp protection & shutdown.
  • End-of-lamp-life (EOLL) detection & shutdown

Product Description

Product Features

  • Energy Efficient Low Frequency square wave Electronic ballast for HPS/MH/CMH/CDM-T lamp types.
  • Retrofit one box solution that replaces Magnetic Ballast, PF improvement Capacitor & Ignitor.
  • Constant Power Output to Lamp over a wide input voltage range (90V ~ 305V AC).
  • High Power Factor with value 0.98.
  • Low Harmonic Distortion with THD value 5%.
  • Flicker free lamp operation.
  • Maximum lamp life as a result of optimal lamp operation.
  • Lamp power and current control.
  • ASIC Control for Ballast operation and Lamp protection
  • Compact metal stamping housing for use inside of luminaires with reduced dimensions
  • Suitable for standard & lateral fixing with M4 screws
  • Easy installation and wiring due to screwless terminals.
  • Controlled ignition time interval (21 sec High & 64 sec Low) attempt stops after 20 minutes. Main supply must be switched OFF and ON to reset the ballast.
  • Comprehensive warranty.
