4kW FM Transmitter – BSE4K-LD2

The BSE4K-LD2 utilizes ‘State-of-the-Art’ LDMOS technology that provides outstanding efficiency and reliability. The BSE4K-LD2 is based on two AL4-2000LD RF Amplifiers each capable of delivering in excess of 2kW. Each amplifier has a built-in SMPS rated at 3kW with PFC control and efficiencies of > 90%. The exciter/driver for the transmitter is the EX-12D 12W FM Exciter with built-in stereo encoder. An optional ESU-1 switching unit and EX-12D can be used when dual exciter configuration is required and provides automatic switching to the standby exciter. The BSE4K-LD2 utilizes a wideband, 2 way RF Combiner, model SC4 2 way. This unit includes the output coupler and circuitry for
forward and reflected power measurements. Mains supply single phase 230V or 3 phase 220V between phases and neutral spread across the various modules.
