Mega Saver

Devtech Megasaver (DMS) is an unique energy saving product used to drive High intensity Discharge lamps (MH / HPS / CMH/ CDM – T/ CXL). It is a retrofit, single box solution which replaces conventional ignitor, PF capacitor, magnetic coil. It gives a constant light output for wide range of input voltages, lower THD (less than 10%) and Power Factor of near Unity (>0.98). The USP of the product is it can match the Lumen level of existing higher wattage lamps with Devtech Megasaver of lower wattage. Example 400W Magnetic Ballast with 400w HID lamp can be replaced with 250W Devtech Megasaver and 250w HID lamp to give similar lumen levels thus saving 40% energy. DMS is also protected for all the vulnerabilities like Short circuit, transient surge, inrush current. Devtech Megasaver is available in ratings like 35 to 400 Watts. This product ensures energy savings up to 40% under most of the operating conditions . Devtech Megasaver can be placed at a distance of 50 meters from lamp so serviceability is an easy task. Pre-programmed scheduling of lamps can be achieved through easy settings.The product can be supplied with IP65 Ingress protection rating. This product is backed by Two Year replacement guarantee.


Protection Features

  • External 10kV/5kA Surge Protection Device (Model – DSG 1510)
  • Lamp over voltage protection & shutdown
