PT-200Ts-V

PT-200Ts-V aircraft electromechanical converter

PT-200Ts-V is an aircraft three-phase electromechanical current converter, also known as a rotary inverter or motor-generator converter. The unit converts DC power from the aircraft onboard electrical network into three-phase AC power. It is used to supply aircraft instruments and systems that require stable 36 V / 400 Hz three-phase alternating current. The converter belongs to the PT-200Ts family of aviation power converters used on Soviet and post-Soviet aircraft and helicopters.

Power conversion function of PT-200Ts-V

The main function of PT-200Ts-V is conversion of 27 V DC aircraft power into 36 V three-phase AC power at 400 Hz. This type of power is required by gyroscopic instruments, attitude indicators, heading systems and other flight-navigation equipment. The converter provides centralized power supply for equipment that cannot be powered directly from the aircraft DC network. Since the unit is electromechanical, output stability depends on the condition of the motor-generator assembly, bearings, brushes and electrical circuits.

Consumers powered by PT-200Ts-V

PT-200Ts-V is mainly used to power spatial orientation and navigation equipment. The supplied context lists aircraft attitude indicators such as AGB-3K, AGR-72 and AGR-74, gyroverticals such as TsGV-4 and TsGV-10, gyroscopic heading instruments such as GPK-52, course system elements such as GMK-1G and KS-8, and autopilot-related attitude sensors used in systems such as AP-6E or AP-34B. The exact consumers depend on aircraft type, wiring configuration and installed avionics package.

Application on aircraft and helicopters

The PT-200Ts-V converter and related PT-200Ts series units are used on Soviet and Russian aircraft and helicopters of civil and military classes. The supplied context mentions An-24, An-26, An-30, An-32, An-12, An-72, An-74, Tu-134, Tu-154, Il-76, Mi-8, Mi-24, Mi-26, Ka-27 and Ka-32, depending on configuration and documentation. Applicability should always be checked against the aircraft illustrated parts catalogue, electrical diagrams and equipment list for the specific aircraft.

Installation area of PT-200Ts-V

The installation location depends on the aircraft type. In many aircraft, PT-200Ts-V is installed in radio compartments, avionics bays or technical equipment compartments. In the supplied context, An-24 / An-26 installation is described on the left side in the radio equipment compartment, usually between frames 11 and 13. On Mi-8 helicopters, the converter is described as installed in the fuselage radio compartment on equipment racks. The unit is mounted to an aircraft frame or shelf designed for vibration and electrical equipment loads.

Construction and maintenance of PT-200Ts-V

PT-200Ts-V consists of a four-pole DC electric motor and a synchronous three-phase generator combined in one housing. This motor-generator construction allows the unit to create stable three-phase AC output from the DC bus. Maintenance should include inspection of bearings, brushes, collector / commutator surfaces, connector condition, insulation, mounting integrity, vibration, heating, output voltage and frequency. For replacement or bench testing, the exact series, aircraft application and documentation package should be confirmed.
