.: Midnight

Concept:

Eltam has responded to the market's demand for an autonomic dimming ballast which does not require an additional control system.

The EHID MidNight brings an innovative concept to energy saving with a short ROI.

The energy savings is realized through adaptive behavior and programmable dimming schedule.

Main advantages:

  • Ease of installation
  • Simplicity - Plug & Play solution
  • No need for an external controlling device, but still enables dimming applications
  • Remote configuration
  • Custom solutions made and controlled by the end customer
  • Totally independent and autonomous system
  • Easily reconfigurable at the site - from the main cabinet
  • One shot configuration (all ballasts), which are not bound to one fixed scenario
  • Appropriate solution for retrofit projects
  • Consideration of lamp deterioration

    • Technology:

  • Innovative technology that enables one way communication to the ballast to create dimming    profiles.
  • Remote configuring of several parameters - the lamp operating power level (On Level and Dim    Level) as well as the Start and End time of the dimming.
  • imming profiles can be changed and determined by a sequence of switching the ballast On/Off by    manipulating the existing activation contactors
  • Configuration is carried out on the existing power lines
  • All the ballasts can be reprogrammed remotely
  • EHID Midnight™ algorithm constantly calibrates and adjusts the preprogrammed dimming    schedule
  • The EHID Midnight™ enables a wide flexibility of dimming scenarios & dimming levels
  • System Architecture: There are three ways to configure the MidNight ballasts (remote    broadcasting):
       1. Manually – by physically manipulating the main contactor
       2. Local computerizing - Configuration Technician Tool (CTT), aided by computer Software.
       3. Remote configuration system – The ON-SiTE

    • Communication Example

    The following example demonstrates remote broadcast of data to the ballasts (all ballasts).The ballast is instructed to operate as follows:
    •Midnight mode
    •Start two hours before midnight
    •Continues until three hours after Midnight
    •Output level of 75%
    •PowerOnLevel = 90% Lamp Power

    CTT - Configuration Technician Tool

    A new configuration may be sent locally by using the CTT.
    By plugging the portable tool into the feeder pillar, a new scenario can be sent to all ballasts. The CTT consists of a PC program.
    An additional use of the CTT is to configure a desired scenario in the ballasts in the pre-assembly stage.    		 CTT
