Avionic Services HPT
2000 constant current regulator (CCR) is designed for
application in aerodrome Ground Light (AGL) systems where
6.6Amp constant current circuits are used.
HPT 2000 is fully compliant with
- ICAO annex 14
- Volume 1 and 2
Part 5 Electrical Systems
Emergency towers
- ICAO Aerodrome Design Manual
- FAA Document
- L-828/829:AC150/5345-10E
- CAP (UKCAA)
- Document CAP 168
Design of the HPT
2000 features micro-controller regulations of the output
current. A sample signal is fed back from the CCR’s output
and the micro-controller. The micro-controller then adjusts
the current flow through a pair of Thyristors which are in
series with the input winding of the main power transformer.
The CCR operates as a simple phase control unit.
An extensive range
of output power (KVA) rating is available and transduction
versions can provided in place of Thyristor based models if
required.
The HPT 2000 has
been designed to ensure easy access for installation and
maintenance.
