2200 VA DC - AC Sine Wave Inverters

Designed for space-limited applications within the telecommunications, data processing and utility industries, the Model 1747 DC-to-AC inverter provides up to 2,200 volt-amperes in only 3.5 inches of vertical rack space. The inverter produces a well- regulated 115-VAC, frequency-stable 60-Hz sine-wave output (50Hz models are also available) from station batteries or other DC sources. Standard versions permit operation from either positive or negative 48-VDC or 130-VDC sources because the DC input is galvanically isolated from the ac output and from the chassis. The inverter is compact, lightweight and compatible with either 19-inch or 23-inch equipment racks.

Series 1747 DC - AC Sine Wave Inverter

  • 48 or 130 VDC input
  • Height 3.5” (2 rack spaces)
  • Isolated, regulated low-distortion output
  • Quartz clock frequency stability
  • Approximately 90% efficient
  • External auto-transfer switch available for UPS / redundant-power applications

1000 VA DC - AC Sine Wave Inverters

The inverter’s low-distortion sine-wave output makes it particularly well-suited for powering sensitive electronic loads, such as telecommunication and data processing equipment (with or without power-factor-corrected power supplies), as well as loads normally considered difficult for inverters, such as small motors.

Series 1746 DC - AC Sine Wave Inverter

  • 24, 48 or 130 VDC input
  • Height 1.75” (1 rack space)
  • Isolated, regulated, frequency-stable output
  • Approximately 90% efficient
  • Rugged, conservative design
  • Available with integral high-speed transfer switch for UPS/standby-power applications

500 VA DC - AC Sine Wave Inverters

The inverter’s low-distortion sine-wave output makes it particularly well-suited for powering sensitive electronic loads, such as telecommunication and data processing equipment (with or without power-factor-corrected power supplies), as well as loads normally considered difficult for inverters, such as small motors.

Series 1745 DC - AC Sine Wave Inverter

  • 12, 24, 48 or 130 VDC input
  • Height 1.75” (1 rack space)
  • Isolated, regulated, frequency-stable output
  • Highly efficient, convection cooled
  • Rugged, conservative design
  • Available with integral high-speed transfer switch for UPS/standby-power applications

1000 VA DC - AC Sine Wave Inverters

Compact and rugged, the 1000-VA Model 1756 DC-to-AC inverter is designed to perform equally well in stationary and mobile applications. The inverter provides an isolated, regulated 120-VAC, frequencystable 60-Hz sine-wave output and is available in 24, 48 and 130-VDC input versions. The conservatively rated Model 1756 can operate continuously at maximum rated power over a -10°C to +50°C ambient temperature range. It is well suited for powering a variety of loads, from sensitive electronic equipment to small motors and nonlinear loads normally considered difficult for inverters. The Model 1756 is available as a plain inverter or with built-in automatic load switchover features to permit operation in UPS or standby-power modes.

Series 1756 DC - AC Sine Wave Inverter

  • 24, 48 or 130 VDC input
  • Isolated, regulated, frequency-stable output
  • Appoximately 90% efficient
  • Rugged, conservative design
  • Available with integral high-speed transfer switch for UPS/standby-power applications
