Optimum lamp operation and economy with ECGs from OSRAM

Electronic control gear (ECG) for operating metal halide lamps offer huge benefits in terms of operation and simple installation. This applies above all for POWERTRONIC ECGs from OSRAM. They are the first choice particularly for operating metal halide lamps with ceramic burners because their outstanding technology releases the full potential of these modern lamps and they are extremely energy efficient.

Benefits of POWERTRONIC ECGs

improved economy

• Up to 15% greater system efficiency compared with conventional control gear
• Up to 20% better luminous flux maintenance and smaller spread of luminous flux compared to conventional control gear
• Up to 30% longer lamp life compared with conventional control gear

Greater energy efficiency

Thanks to their optimized circuit design POWERTRONIC ECGs have a low power loss. The system wattage is up to 15% lower than with conventional control gear (CCG), which translates into considerable energy savings. The reduced thermal output also reduces the load on the air-conditioning system – double savings!

Simpler installation

With conventional control gear three components have to be connected. POWERTRONIC ECGs offer uncomplicated connection - the ac line and lamp cables have to be connected to just one device. The models with strain relief offer very simple wiring because of the through-looping option.

Flickerfree light

Metal halide lamps operating on conventional control gear may flicker. POWERTRONIC ECGs operate at a frequency of 160 - 180 Hz and provide pleasant flickerfree light.

Smaller dimensions

POWERTRONIC ECGs combine miniaturized components, a highly integrated microcontroller and small dimensions – a significant driving force for new compact and stylish fixture designs.

Smaller drop in luminous flux

Lamps operated with POWERTRONIC ECGs have up to 20% better lumen maintenance throughout their lives compared with conventional control gear. This is due above all to gentler lamp starting and the constant output of the ECG.

Near silent operation

POWERTRONIC ECGs produce very little noise in operation. This is important particularly in retail and presentation applications. Conventional control gear on the other hand have a tendency to produce mechanical oscillations owing to their design. In some cases this leads to considerable noise.

Greater color stability

Intelligent lamp control and the constant output of POWERTRONIC ECGs, unaffected by fluctuations in voltage, provide better color stability throughout the life of the lamp compared with CCG operation.

Longer lamp life

Optimized gentle lamp starting by POWERTRONIC ECGs in combination with constant output and the absence of reignition peaks prolongs the life of the lamp by as much as 30%.

Intelligent and reversible thermal protection

Very high temperatures can occur in compact fixtures. POWERTRONIC ECGs are equipped with an intelligent power regulation system and reversible automatic disconnection circuit to protect the ECGs against overload in such critical situations.

No annoying restart attempts

If metal halide lamp lamps are operated on conventional control gear they tend to switch on and off periodically at the end of their lives. This can be very annoying, particularly during presentations and in retail outlets. There is no chance of this happening with POWERTRONIC ECGs because the lamp is disconnected at the end of its life after a maximum of three ignition attempts per starting procedure.

Safe shutdown of the lamp

When metal halide lamps are operated on conventional control gear there is no communication between the control gear and the lamp. If the lamp is in an abnormal operating state this can lead to overheating and destruction of the CCG. POWERTRONIC ECGs on the other hand permanent monitor important lamp parameters such as the lamp current and the lamp voltage and can rapidly disconnect the lamp in such cases.

Unique: OSRAM System⁺ Guarantee

If OSRAM ECGs and OSRAM lamps are used together, OSRAM offers a guarantee on the electronic control gear and illuminants (OSRAM System⁺ Guarantee). Registration is required.

Typical applications of POWERTRONIC ECGs

Accessories: EBN-OS for POWERTRONIC ECGs

The EBN-OS inrush current limiter restricts the current through electronic control gear when the ECG is switched on, which means that a larger number of ECGs can be connected to an automatic cutout. EBN-OS has been designed exclusively for POWERTRONIC ECGs.

• Up to 2.5 times more ECGs on an automatic cutout
• Limitation of capacitive inrush currents
• Maximum continuous load: 16 amps
• Inrush current limitation time: 70 ms
• Dimensions in millimeters: 18 x 88 (45) x 58
• Design: DIN rail casing
