For Use With
Three (3) or Four (4) F17T8, F25T8, F32T8 Lamps
Model PES277HPT8-4
Uses an electronic technology with the state of the art
semiconductors resulting in an ENERGY SAVING
electronic ballast for FOUR F32T8 lamps. When
compared to conventional magnetic ballast, this ballast
can accomplish up to 25% in energy savings.
High Power Factor & Low THD Performance
The PES277HPT8-4 designed to provide HIGH power
factor [> 0.98] and LOW THD [< 20%] for 277 VAC utility
lines. This feature helps the utility companies to
distribute noise free and reliable power to equipments.
The reliability and superior performance and lamp long
life is achieved by allowing low operating stresses and
high temperature rating.
Noise Free Operation
The microelectronics system design provides a NOISE
FREE and quiet ballast performance. Higher frequency
operation enhances the light output for the same
power level, compare with standard magnetic ballasts
60Hz noisy and power inefficiency operation.
Electromagnet Interference (EMI)
The PES277HPT8-4 ballast consists of AC line filters to
suppress high frequency noise feeding into AC power
lines. The ballast filtering has been designed to comply
with the latest FCC Consumer B requirements for
residential and commercial applications.
Testing and Reliability
The PES277HPT8-4 design is tested rigorously for long
life and reliability. PES277HPT8-4 has been tested
through continuous cycling. It has successfully
completed 50,000 cycles of operation with FOUR F32T8
lamps. The ballast design has been further tested at
50°C ambient in a chamber for long periods. The ballast
has also been tested in simulated ceiling fixtures at
worst case conditions for extended periods while
monitoring component temperature limits for all
components.
Case Size & Installation
Mechanical dimensions and case size are smaller than
standard ballast in the market. Suitable for retrofitting
and new installations.
