Line frequency converter HS50

for aeronautical maintenance

The HS and HB series are lightweight, AC frequency power converters. These models utilize the latest state of the art solid state circuitry to convert a 115/200 VAC, 3 phase, 400 Hz input to either a 115 VAC, 60 Hz or 230 VAC, 50 Hz sine wave output. Design features include a crystal controlled oscillator for output frequency stability and a pulse-width-modulated square to sine wave power conversion scheme for efficient & reliable operation. The model HS and HB Series frequency changers are designed to power laptop computers, audio/video entertainment systems, portable electronics (stereo, MP3, CD, DVD, video games, etc.), microwave ovens, coffee makers and medical equipment in mobile, marine and ground transport applications Specifications Input Voltage 115/200 VAC ± 10 VAC, 3 phase Input Frequency 400 Hz ±100 Hz Output Wave Form Sine Output Phase Single Harmonic Distortion 0.5% (nominal) Power Factor +.8 to -0.8 Efficiency 87%(nominal) Response Time 300 uSec (no load to full load) Regulation 1% Line, 1% Load, 2.5% Temp. Overload Capacity 110% of the rated output power for a period of 2 hours; 150% of the rated output current for a period of 5 minutes (minimum). When the operating temp. >55°C, the overload setting is internally limited to 135% ± 10% of the rated output power. Protection Circuits The converter will shutdown under the following conditions: Input voltage > 135 VAC ± 5 VAC Input voltage < 95 VAC ± 5 VAC Internal, high ambient temperature.
