Voltage Transients
The RP100V series includes internal protection against voltage transients due to lightning and other AC power line surges, as indicated on page 2. In some applications such as highway lighting where there may be an unusually high level of power line surges, it may be necessary to use additional surge protection external to the power supply. This protection can be achieved using surge suppressors such as Transzorbs or MOVs connected across the AC input terminals of the power supply. Outdoor Environment
The RP100V series is mounted in an IP67 enclosure for use in damp locations. This enclosure is suitable for applications where the PSU is not well protected and may be subject to water splashing directly onto the PSU enclosure. For applications where the IP67 housing is not required, please consult AEG Power Solutions.
Safety
The RP100V series meets North American and international safety specifications at the component level, and is certified according to UL, cUL and CE. It is designed to be mounted inside a final product enclosure and it is the user’s responsibility to obtain safety approval for the final product. The power supply includes an internal input fuse. Additional external protection may be needed in some cases, depending on the details of the application.
Mounting
The RP100V series is designed to be mounted to a metal surface that can act as a heatsink, such as the housing of a luminaire. It is recommended to carry out testing in the final configuration to confirm that the ambient air temperature is not excessive under worst-case operating conditions. If the ambient exceeds +70°C the thermal protection may cause the unit to shut down. AEG Power Solutions can provide assistance with thermal design and simulation if required. | |
Dimming
The RP100V series does not support dimming. If your application requires dimming, AEG Power Solutions has other products available that can be dimmed through industry-standard dimming interfaces.
Derating
The RP100V series is designed to provide very high reliability and long life under all normal operating conditions. All components used in the design are operated well within their ratings, following AEG Power Solutions derating policy. No further derating of the power supply is necessary as long as the ambient does not exceed +50°C. If the ambient temperature exceeds +50°C, derating is required as shown in Figure 1.
Reliability
The MTBF prediction given on page 2 of this datasheet assumes long-term operation at 100 % load, with an ambient temperature of +25°C. Short-term excursions above this temperature will not significantly affect the MTBF, provided the maximum rated ambient temperature is not exceeded. If the power supply is used in an environment where the sustained operating temperature is significantly higher than +25°C, the MTBF will be reduced accordingly. For example, at an ambient temperature of +45°C the MTBF is reduced by approximately 4X. In many lighting applications the lights are only on for a portion of the day, and the power supply lifetime will be extended in proportion.
