In addition to gyro flight instruments, Castleberry Instruments & Avionics provides a new line of electronic aircraft components now offered as improved replacements to older units from other manufacturers.
EMERGENCY POWER SUPPLY Included in the lineup is the TSO’d emergency power supply, the Model EPU 28-24RMT series. This emergency power supply produces a 14-, 24- or 28-VDC output for emergency power for instruments including a gyro display and a radio in case of total aircraft electrical system failure. This is economical insurance in a 7.5 pound package for aircraft frequently involved in IFR operations. This EPU replaces the non-TSO’d Terra and AIM units that are no longer in production.
INVERTERS Castleberry now also produces the PAC-75, a new 28-VDC electrical inverter. This 115 volt, 400 cycle, 75 watt unit is designed to replace older units which have reduced power capacity. The PAC-75 inverter is a TSO’d replacement for non- TSO’d units including, AIM P-20, -21, and -21A.
