500 VA Sinewave DC - AC Inverters (1U)

Conservatively rated, electrically rugged and highly efficient, the Series 1745 and 1765 DC-to-AC inverters provide a regulated, frequency-stable, 120-VAC sine-wave output at up to 500 volt-amperes. Standard versions of the inverters permit operation from 12, 24, 48 or 130-volt station batteries or other widely fluctuating DC sources in ambient temperatures up to 50oC. Series 1745 inverters are not metered, whereas Series 1765 inverters feature a front-panel output meter that displays voltage, current, real power and power factor.

The inverters’ low-distortion sine-wave output makes them 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. Both the Model 1745 and the Model 1765 are available as a plain inverter or, optionally, as an inverter that features built-in automatic load switchover capability to permit operation in UPS or stand-by power modes.

2200 VA Sinewave DC - AC Inverters (2U)

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 24-VDC, 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.

The Model 1747 is well-suited for powering a variety of loads, from sensitive communications and SCADA/telemetry equipment to loads normally considered difficult for inverters, including small motors and other reactive or high-surge loads. With the addition of Wilmore’s Model 1747-ATS automatic transfer switch, the inverter can function as the primary or backup ac source for applications requiring uninterruptible/redundant power. Conservatively designed and well-protected against external faults, the Model 1747 DC-to-AC inverter is ideal for powering waveshape-sensitive and frequency-sensitive AC loads from DC power systems.

200 and 400 Watt Single-Output DC - DC Converters (1U)

These single-output converters provide a well-regulated DC output voltage from station batteries or other widely fluctuating DC sources. This output is galvanically isolated from the source and chassis and, therefore, may be connected either as a positive or a negative output. Applications include powering radio transceivers, telecommunications equipment, supervisory control systems and other critical electronic loads.

Designed for rack mounting, these state-of-the-art converters achieve superior electrical performance in a low profile enclosure. Conservatively rated and very efficient, Series 1720/1760 converters will operate continuously at any load within their rating over a wide ambient temperature range with simple convection cooling. They are available with (Series 1760) or without (Series 1720) front-panel output meters, and additional standard options let users adapt converters to specific system requirements, including paralleling for redundancy and for additional power.

High Isolation Single-Output DC - DC Converters (1U)

These single-output converters supply a well-regulated DC output voltage while providing a high-voltage (2,200VAC) isolation between input to output and input to chassis. This output is galvanically isolated from the source and chassis and, therefore, may be connected either as a positive or a negative output. Applications include powering radio transceivers, telecommunications equipment, supervisory control systems and other electronic loads requiring a high degree of electrical isolation from the DC source.

Extended Input Range DC-DC Converters

Series 1640XR DC-to-DC converters provide an isolated, regulated and well-filtered DC output voltage from nominal 24V, 48V, and 130V battery systems. This output is galvanically isolated from the source and chassis and, therefore, may be connected either as a positive or a negative output. Two available input-voltage ranges (20V-80V and 40V-150V) allow one version of the converter to cover multiple battery voltages. Designed to perform equally well in mobile and stationary applications, these converters can be used to power radio transceivers, telecommunications equipment and other sensitive electronic loads. Models with outputs of 13.6 VDC and 24 VDC are described in the product bulletin.

Locomotive Voltage-Boosting DC - DC Converters

Model 1741-60-3.5 and Model 1741-60-7 DC-to-DC converters are designed to allow nominal 74-volt locomotive equipment to operate through low-input-voltage conditions or on-board 37-volt or 24-volt rail vehicles. When the converter’s input voltage drops below 60 VDC, the converter automatically boosts its output voltage to 60 VDC to continue powering equipment connected to it. At input voltages above 60 VDC, the converter provides additional filtering and transient protection without substantially altering the input voltage. Conservative electrical design, very high operating efficiency and rugged mechanical construction make these converters well suited for powering voice/data radios and other sensitive electronic loads in the harsh railroad vehicle environment.
