OMB EM 25000 HE DIG

El OMB EM 25000 HE DIG 25KW FM transmitter has been created by the OMB center of development for high efficiency transmitters.

El OMB EM 25000 HE DIG 25KW FM transmitter has been created by the OMB center of development for high efficiency transmitters. It consists on the high efficiency 25KW amplifier, FMA 25000 HE, and the EM 250 DIG PLUS, a 250W FM transmitter. The high efficiency 25KW amplifier is composed by eight 3.5KW amplifying stages (FMA 3500 HE). This transmitter can be supplied with the following options:
– Stereo generator
– RDS
– Web server/SNMP telemetry
– AES/EBU digital audio input

MAIN ADVANTAGES:
– Eight amplifying units, each composed by four amplifying modules of 1.200W with robust LDMOS transistors of the latest technology.
– Each amplifying unit contains three independent switching power supplies connected in parallel to maintain the equipment working in case any of them fails.
– Pantalla TFT y teclado táctil para controlar y visualizar los parámetros de funcionamiento.
– Grabación de eventos en la memoria.
– 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.
– Telemetría analógica, control remoto digital y telemetría RS232, control remoto mediante contactos de apertura/cierre.
– Automatic power reduction at night when used in combination with the EM 250 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.
– Reducción automática de la potencia en caso de potencia reflejada excesiva.
