TridonicAtco have launched the ZRM ES/C series of fully rounded ignitors for the operation of all standard high-pressure discharge lamps with outputs from 35W to 2000W. When compared to the previous generation of ignitors, the casing dimensions of the ZRM ES/C units have been reduced whilst the thermal behaviour has been maintained or improved, making them extremely cost effective to use.The range includes the ZRM 2-ES/C, ZRM 2.5-ES/C and ZRM 4.5-ES/C ignitors for outputs of 35W to 400W in standard applications. For temperature-critical or low noise applications, TridonicAtco has included the high performance ZRM 6-ES/C ignitors in the new range, in addition to the ZRM 12-ES/C version, which has been engineered for high-end output from 400W to 1000/2000W. The compact dimensions and optimised thermal behaviour of the ZRM 12-ES/C also makes it ideal for use with compact luminaires. For added safety, a snap-on terminal cover is available for ZRM ES/C ignitors that prevents the terminals being touched accidentally.
The ZRM ES/CT option has a digital timer that monitors the ignition process and the behaviour of the lamp. The starting phase of the first time interval has been extended from 10 seconds to three minutes to meet the demands of future light sources. The new ignitors also have a three start counter that detects the lamp cycling that can occur when a lamp reaches the end of its life and terminates the ignition process after the light has gone out three times; an automatic reset function has also been integrated into the digital ignition control system.
The auto-reset function on TridonisAtco's ZRM ES/C ignitor range is particularly important if high pressure discharge lamps are employed in round-the-clock applications, such as tunnels or factories, as control gear should not be disconnected from the power supply without good cause. Auto-reset ensures that a light source that has gone out can be reliably restarted.
TridonicAtco has also developed the ZRM 6-ES/C 400 and ZRM 12-ES/C 400 ignitors for specialist applications such as commercial greenhouses that are often operated at an ac voltage of up to 400V, enabling the installation of up to 10,000 lumiaires per greenhouse.
