Ground Platforms

Espey is fully compliant to the Army Ground Mobile specification, and has fielded nearly 1000 sets of Power Conditioning/Battery Charger assemblies and Digital Fire Control Electronics for the Army’s successful Lightweight 155mm Howitzer from BAE. We have produced hot swappable and uninterruptible power supplies, multiple voltage DC to DC converters, dry and liquid cooled transformers and antennae assemblies for such notable ground applications as:

  • Lockheed-Martin TPS-79 MMSR Radar
  • Raytheon Patriot Missile
  • BMD and THAAD radar system
  • Lantirn ER targeting pod
  • NATO Early Warning Radar full rack transmitter (build-to-print)

DC/DC Power Control and Conditioning Module (Ground Based Artillery Artillery)

Product ID: PCCM

The PCCM will provide a nominal output voltage of 28Vdc, when external DC power is connected. Output power distribution is accomplished through branch output circuits that are independently controlled by commands over an EIA-422 data bus from the controlling computer, which also monitors PCCM operational status. While the external DC power source is connected, the PCCM is also capable of providing battery charging for a 24Vdc Lead Acid battery configuration. When the DC power source is not connected and the battery is charged, the PCCM uses regulated DC power from the Battery to supply a nominal branch circuit output voltage of 28 Vdc. The PCCM also provides operator interfaces that control power selection and distribution to its external loads, as well as visual status indications.

Radar Transmitter - NATO Ground Based Artillery

Product ID: SP-45K4-PS

Espey developed this, solid state, high voltage power supply, as the major subsystem of a 150 kW, 8.8% duty cycle, coherent S-Band TWT radar transmitter system. The solid state 45 KV DC power supply is rated at 60kW average output power at 19 amps peak for pulse widths from 8 to 300 microseconds. The two-cabinet system is fed through a soft-start module and multiple, cold plate cooled individual switching regulator/inverter modules in the power and control cabinet. These solid state switching regulator/inverters drive the high voltage transformer which form the 45 kV high voltage power supply. A unique variable boost in conjunction with a fixed supply provides better than 1% regulation at 45 kV with extremely low pulse to pulse jitter of less than 3 volts for narrow pulses. The high voltage cabinet houses the TWT and associated high voltage assemblies including, the high voltage transformers, high voltage divider and energy storage capacitors. Dual microprocessors control the touch panel electroluminescent digital readout display in the control cabinet as well as the monitoring and fault protection circuitry.
