Description
PTS-800AM converter in aircraft power systems
The PTS-800AM is an aircraft three-phase static converter used as a secondary power source for onboard equipment. It converts 27 V DC from the aircraft electrical network into three-phase 36 V AC at 400 Hz. This type of power is used by flight instruments, navigation equipment, radio-electronic units and other systems that cannot operate directly from the DC bus. In the aircraft electrical system, the PTS-800AM works as a dedicated inverter for equipment requiring stable low-voltage three-phase alternating current.
36 V output of the PTS-800AM
The key feature of the PTS-800AM is its 36 V three-phase AC output. This separates it from related versions in the same converter family that provide other output voltages. When selecting a replacement unit, this point is critical: a converter with the same power rating but different output voltage is not a direct substitute. The aircraft wiring diagram, equipment power requirements and parts catalog must be checked before installation. The PTS-800AM should be selected where the connected onboard consumers require three-phase 36 V, 400 Hz power.
PTS-800AM for avionics and instrument equipment
The PTS-800AM is used to feed low-voltage AC consumers in aircraft instrument and radio-electronic systems. On helicopters of the Mi-8 / Mi-17 family, converters of this type may be installed in equipment racks or technical areas together with navigation, communication and electrical units. The converter provides the required AC supply for equipment that must receive a steady sinusoidal voltage at aircraft standard frequency. Stable output is important because sensitive instruments and avionics blocks can react badly to voltage distortion, frequency deviation or unstable supply under load.
Static design of the PTS-800AM
The PTS-800AM is a static semiconductor converter. It has no rotating motor-generator assembly, so there are fewer mechanical wear points compared with electromechanical converters. Inside the unit are the master oscillator, inverter stages, voltage stabilization circuits, radio-interference filters and cooling elements. This design allows the converter to form a three-phase sinusoidal output from the DC input while keeping the unit compact enough for aircraft installation. During maintenance, technicians usually pay attention to output stability, heating, fan condition, connector condition and signs of internal electrical stress.
Installation of PTS-800AM on aircraft
The converter is installed in technical compartments, radio equipment bays, avionics racks or cabin equipment areas depending on the aircraft type. On Mi-8 / Mi-17 / Mi-26 helicopters it may be located in the cargo or passenger cabin area near equipment shelves on the left or right side. On aircraft such as An-24, An-26, Yak-42 and Tu-142, the unit is installed in electrical or radio-technical equipment compartments according to the aircraft layout. Exact placement depends on the approved installation documentation and aircraft modification.
Mounting frame and vibration protection for PTS-800AM
The PTS-800AM is normally mounted on a shock-absorbing frame or support with vibration isolators. This protects the converter from vibration and mechanical loads that occur during flight, takeoff, landing and ground operation. A rigid but vibration-isolated installation is important for the electronics, connectors and internal assemblies of the converter. In service, the frame should be checked together with the converter itself. Loose locks, damaged vibration isolators, poor grounding or stressed cable routing can create faults that look like converter problems but are actually installation-related.
Protection and service checks of PTS-800AM
The PTS-800AM is intended for continuous operation and includes protection against short circuits and overload conditions. It can withstand a short-term overload within specified limits, but this does not mean the converter should be operated above rated load continuously. If the unit trips, overheats or gives unstable output, the connected load and wiring should be checked before replacing the converter. A short circuit, insulation fault, blocked cooling airflow or overloaded consumer can damage the converter or cause repeated failures after installation.
