POWER APPLICATIONS

Compact and rugged, the 1000-VA Model 1725 dc-to-ac inverter is particularly suited for space-limited applications within the tele-communications, data-processing and utility industries. Occupying only 1.75 inches (1U) of vertical rack space, this inverter provides a regulated 120-Vac, frequency-stable 60-Hz quasi-sine-wave output.

It is available in 24, 48 and 130-Vdc input versions and is compatible with either 19-inch or 23-inch equipment racks. The conservatively rated Model 1725 can operate continuously at maximum rated power over a -10°C to +50°C ambient temperature range and 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 1725 is available as a plain inverter or with built-in automatic load switchover features to permit operation in UPS or standby-power modes.

SPECIFICATIONS

Input Voltage and Current The nominal input voltage, the input voltage range, the no-load input current and the full-load input current are shown in Table 1.

Output Voltage 120 Vac nominal, single phase

Frequency 60 Hz nominal. ±0.25 Hz maximum variation over the full range of load and input voltage changes. Temperature coefficient is ±0.02% maximum per °C.

Volt-Ampere Rating

1000 VA

Output Voltage Regulation Approx. ±5%

Output Voltage Wave Shape Three-level stepped approximation to a sine wave with peak, average and rms values approximating those of a sine wave.

Temperature Range Operating: -10°C to +50°C Storage: -40°C to +95°C

Protection Protection against overloads and accidental short-circuit of the output is provided electronically, and recovery is automatic upon removal of the abnormal load.

Front-Panel Controls and Indicators A combination circuit breaker and ON/ OFF switch is provided for input power.

L and U versions include three LED status indicators.

Mechanical Description Figure 1 provides overall dimensions.

Weight is approximately 13 lbs. Brackets are provided for 19-inch or 23-inch rack mounting.

Standard Configurations P VERSION: Adding the suffix P to the basic model designates a plain inverter, i.e. a unit with no internal inverter-to-line or line-to-inverter transfer switching provisions. (“Line” refers to commercial ac power.) This version does not have the three front-panel LED status indicators or alarm contacts.

there is a delay of approximately five seconds, the load is then transferred back to commercial ac power and the inverter again operates in the standby mode.

Other features such as transfer speed, alarms, indicators, etc. are the same as in the U version.

Model Numbering Information For ordering purposes the Model 1725 should be identified by an expanded model number consisting of four numbers followed by a letter suffix. In sequence, they designate:

• basic 1000 VA inverter type (1725)

• nominal input voltage (24, 48 or 130)

• nominal output voltage (120)

• output frequency (60)

• configuration (P, U or L version) For example, the correct part number for a 48-volt input, inverter-preferred UPS configuration is Model 1725-48-120-60-U

Information provided in this bulletin is subject to change without notice.

U VERSION: Adding the suffix U to the basic model number designates the inverter-preferred UPS configuration.

In this configuration, the load power is normally provided by the inverter.

However, if the inverter output is interrupted, an internal transfer switch automatically transfers the load from the inverter to commercial ac power. The transfer time between inverter and line is short (2 msec. typical) and such transfers are normally not detected by even highly sensitive loads. Upon restoration of inverter power, transfer back to inverter power automatically takes place within a few seconds. This version includes auxiliary Form C contacts for remote indication of alarm conditions and three front-panel LED status indicators.

L VERSION: Adding the suffix L to the basic model number designates a unit which is identical to the “U” version except that, in the L configuration, the load power is normally provided by the commercial ac line and the inverter operates in the standby mode. If commercial ac power is interrupted, an internal transfer switch automatically transfers the load to the inverter.

Upon restoration of commercial ac power, Fig. 1 Overall dimensions. Inverter shown is U or L version.
