E Series
The E series is a family of electronic power conditioners available in three output power platforms, 60W (EA), 100W (EB) and 170W (EC). The targeted applications are solid state power amplifiers (SSPA) and high power amplifiers (HPA) requiring high efficiency performance, specific output sequencing for RF amplifiers, excellent CE and CS EMI performance, on/off command/telemetry, and in-flight output adjustment for optimum efficiency performance.

Applications: SSPA, FGU, Tx, HPA, etc. 18 years life in orbit

Key Features:

  • 3 input ranges 20V – 100V is accommodated by change of the MOSFET type in the full-bridge and the turns-ratio of main transformer.
  • 3 power platforms, 60W (EA)/100W (EB)/170W (EC)
  • Triple outputs, 2 positive, 1 negative (+5V, -5V, main 6-9V).
  • Main output user adjustable during flight operation or tuning on ground.
  • Linear regulators on auxiliary outputs ensures: ultra stable output voltage, low CE-ripple, high CS-rejection and well-defined current limit protection.
  • EMI filter, Provides EMC compliance to various satellite platforms.
  • Use integrated magnetic (patent) and hy-bridge rectification with synchronous rectifiers (patent) ensures high efficiency >90% and low mass
