The powerPAK supply units from TridonicAtco combine ballast, ignitor, p.f. correction capacitor and terminals in a compact casing. These independent units in safety class 2 are very easy to install. No tools are needed at all, so they save an enormous amount of time on site.
All the supply units for operating metal halide lamps or sodium lamps are temperature-protected and are suitable for mounting on normally flammable material (fire category F). The units are preset at the factory for maximum possible voltage tapping. This can be adjusted to the actual supply voltage without the need for any tools.
The robust design also means that the units can be used at high ambient temperatures (ta).
The compact casing design results in exceptionally quiet operation. The supply units are available with or without prewired lamp cables. Screwless terminals make it easier to connect to the mains. Quick fastening of the terminal covers and tool-less cable clamps add up to efficient installation.
The ignitors used are an essential quality feature of the powerPAK series from TridonicAtco. There is a choice of two superimposed-pulse ignitors – the successful standard ZRM ES/C ignitor or the ZRM/CT ignitor with digital timer and pulse-pause operation.
The additional version, the OM PAK “Long distance” supply unit is designed for lighting solutions with high-pressure dis-charge lamps in applications such as retail outlets, churches and doctors’ practices. the integrated ZRM powerPULSE pulse ignitor is extremely quiet in operation and actively regulates the ignition voltage within a narrow bandwidth (± 0.2 kV) with reference to the normal value. The extremely stable ignition voltage curve ensures optimum reliability even for applications with long cable lengths.
OM PAK “Long distance” supply units from TridonicAtco can be installed separately from the luminaires (in suspended ceilings for example) which means they are flexible in terms of where they can be located. This arrangement avoids a thermal build-up and improves weight distribution.
With these different versions TridonicAtco presents a rounded application-oriented range of OM PAK supply units that ensure that high-pressure discharge lamps are operated in accordance with manufacturers’ specifications.
