OMB FMA 2000 HE HPPS

The OMB FMA 2000 HE HPPS 2KW FM amplifier (Hot Plug Power Supply) has been created by the OMB center of development for high efficiency amplifiers. It has >73% efficiency and an approximate consumption of 2600VA at 230Vac, so it pays for itself in a short period of time due to its low consumption.

FEATURES

– Typical AC efficiency >73% and typical RF efficiency of 84%.
– Two amplifying modules of 1.200W with MOSFET technology.
– Two independent switching power supplies connected in parallel to maintain the equipment working in
case any of them fails, removable and interchangeable during operation.
– TFT screen and touch keyboard to control and to visualize operation parameters.
– Memory recording of events.
– Speed control of cooling fans according to temperature of power modules so as to optimize consumption
and to decrease acoustic contamination.
– Advanced protection against load mismatches without transmission cuts and fast protection in case of
excessive reflected power and/or excessive input power.
– Analog telemetry, digital remote control and telemetry RS232, remote control by opened/closed contacts
– Low pass filter, Mains EMI filter and internal single-phase transient suppressor.
– Automatic power reduction at night when used in combination with the EM 25 DIG PLUS transmitter.
– Automatic power reduction in case of high temperature, the equipment returns automatically to its rated
power value when the temperature reaches back an average value.
– Automatic power reduction in case of excessive reflected power.
– Automatic voltage control for efficiency optimization.
– Hot plug and hot swappable power supplies in amplifier.
