Low Profile, Conduction Cooled Inverter Delivers 1,000VA Sine Wave Voltage in Harsh Environments
20 May 2005 15:20
Absopulse Electronics’ PSI 1000 series inverter delivers 1,000VA sinusoidal voltage at 50Hz, 60Hz or 400Hz for driving AC equipment in railway, industrial, marine, mining, utility and aviation ground support applications.
The PSI 1000’s internal modules are fully encapsulated within a thermally conductive MIL-spec. silicon rubber compound to ensure immunity to shock, vibration, moisture, humidity, salt and fog. It is conduction cooled via a base plate and rated for operation with extended temperature ranges. The unit is housed in a low-profile 19in x 14in x 3in chassis-mount enclosure.
This solid state inverter incorporates microprocessor controlled high-frequency PWM technology to synthesize sinusoidal outputs of 115Vrms or 230Vrms and accepts a nominal input of 24V, 36V, 48V, 125V or 250VDC (+20%/-15%). Line regulation is within 0.5% and load regulation is within ±2% from no load to full load. Efficiency is at least 78% at full load. Total harmonic distortion is less than 5%.
The PSI 1000 is filtered to meet the requirements for EN55022 Class A as a minimum. It is designed to meet international safety approvals including C22.2 No. 107.1- 01, UL 458 and EN60950. Protection includes current limiting, short circuit protection and thermal shut-down with automatic recovery in case of continuous overload. An optional output fail alarm (form C) and remote inhibit are available.
