NOTE: The harness is designed to be specific to the instrument used, and aircraft voltage. The correct harness should be selected at time of order. Using the wrong harness will result in voiding the warranty. See chart below for proper harness.

The R.C. Allen Emergency Standby Power unit (ESP) is a battery-based emergency power supply designed to give you at least an hour of auxiliary power to your mechanical gyro and up to 6 hours of power when paired with the RCA 2600 Digital Horizon. The ESP can be easily mounted behind the instrument panel and can be used to power your R.C. Allen instrument, or retrofit your existing Attitude gyro giving you that extra margin of safety when you least expect it.

The ESP comes complete with a wire harness and panel-mounted status light. Maintenance is easy, the unit recharges itself during flight and does not drain the aircraft battery when aircraft power is off. The ESP utilizes a long lasting lithium polymer battery - the same kind found in most laptop computers.
