Pure DC-AC Sine Wave Inverters, AC-AC Frequency Converters - Single & 3-Phase
Pure Sine-wave Inverters,
Phase & Frequency Converters

ABSOPULSE is an OEM of custom, semi-cusom and standard DC-AC sinewave inverters, AC-AC phase converters and frequency converters. They are available in power levels from 30VA to over 15kVA, for 50Hz, 60Hz or 400Hz applications.

Our AC-output designs employ field proven microprocessor controlled high frequency PWM technology to generate the required output power with pure sine wave output voltage. High frequency conversion typically enables compact construction, low weight and high efficiency.

Product reliability is based upon high quality designs, large headroom, the use of qualified-in components with many years of established reliability and compliance with application-specific safety and emissions standards.

ABSOPULSE AC-output products meet the exacting standards of industrial automation, railway, military, marine, mining, utility, telecom, aviation ground support equipment and airborne applications.

Standard AC-output units under 1kVA are housed in rugged, vented, enclosed, combination conduction and convection cooled or fan cooled packages.

Systems with higher output power are typically housed in modular 3U or 6U fan-cooled packages and are available in chassis-mount or 19 rack-mount format. This modular construction facilitates shipping and on-site maintenance.

ABSOPULSE's Inverters, Phase & Frequency Converters feature:

  • Inputs: 24Vdc, 48Vdc, 72Vdc, 110Vdc, 250Vdc
    or custom;
  • Outputs: 115Vac or 230Vac (1-Phase);
    208Vrms, 380Vrms or 400Vrms (3-Phase).
    Custom outputs available;
  • Frequency: 50, 60 or 400Hz or custom;
  • Single or three-phase designs;
  • EMI filtering to meet any standard;

  • Unit/module fail alarms (form C contacts);
  • Remote shut down on certain units;
  • Adjustment for output voltage and frequency;
  • RoHS compliance.


3-Phase Sine Wave Inverters deliver 1kVA

The compact, low cost pure sine wave inverters are suitable for applications that require a low power, three phase AC voltage solution including for 400Hz servo systems to test avionic instrumentation and equipment and for testing small 3-phase equipment ...  Read more




Encapsulated Pure Sine Wave Inverters deliver 300VA in harsh environments

The compact pure sine wave inverters power sensitive electronic loads in mining, transportation, oil rigs and other harsh environments. They deliver single, stable sine wave output of 115Vac continuous at 60Hz or 400Hz, or 230Vac continuous at 50Hz.   Read more




AC/AC Frequency Converter delivers Stable Sine-wave Voltage from "dirty" Generator Voltage

This 2kVA system converts a wide range varying generator voltage of 180V - 270Vac with a frequency range of 35 - 70Hz, to a stable 120Vac at 60Hz, which is required to run control circuitry and instrumentation in heavy equipment vehicles. Read more
