Elgar 441V AC Power Source

The Elgar 441V is a high-performance AC power source designed for a wide range of testing and power applications. It delivers clean, precise, and reliable AC power with excellent stability and control, ideal for simulating various power conditions and testing electronic devices. The 441V model is specifically associated with a plug-in oscillator that provides a fixed frequency output within a defined range.

### Technical Specifications

* **Product Type:** AC Power Source Oscillator Plug-in Module
* **Model Series:** 400 Series (specifically the 441V designation points to a specific oscillator configuration within this series)
* **Frequency Range:** 350 Hz to 450 Hz
* **Phase:** Single Phase
* **Accuracy:** ±0.1%
* **Frequency Stability (Gain Stability):** ±0.25% for 24 hours at constant line, load, and temperature
* **Line Regulation:** +0.25% at full load vs. ±10% change of input line voltage
* **Load Regulation:** +1% from no load to full load over full frequency range and ±10% input range. Adjustable to better than 0.1% for specific load conditions. Fixed frequency systems always less than 0.25%. For crystal-controlled oscillators, line and load regulation are specified at 0.01%.
* **Response Time:** Less than 50 µsec
* **Noise Level:** 70db below full output
* **Output Harmonic Distortion:** 0.6% THD worst case
* **Operating Temperature Range:** -20°C to +50°C
* **Storage Temperature Range:** -40°C to +80°C
* **Power Factor:** +0.7 at full VA
* **Oscillator Type:** Fixed Frequency RC Phase Shift Oscillator
* **Frequency Control:** Typically selected via DIP switches in fixed frequency models. The 441-.01SS model provides a stable 400 Hz signal, with amplitude controlled by an electronic servo to stabilize the AC Power Source’s load voltage. A screwdriver adjustment on the oscillator’s front panel allows for a narrow range adjustment of the output voltage. The AC Power Source’s front-panel amplitude control is inactive when this oscillator is installed.
* **Control/Programming:** For some models, output voltage can be externally programmed with resistance (0-13 kOhms for 0-full scale output) or DC voltage (0-10 VDC for 0-full scale output). Crystal-controlled oscillators may offer ±0.01% amplitude and ±0.1° phase angle stability for 1000 hours.

### Electrical Specifications

* **Input Power:** Typically 115 or 230 VAC at 50 or 60 Hz. Units operating with 400 Hz input power are available on special order.

### Interfaces

* **Connection:** The oscillator is a plug-in module designed to insert into the front-panel opening of Elgar AC Power Sources.
* **External Control (Potentially):** Some oscillator configurations allow for external programming of amplitude and frequency via analog voltage or resistance. A 1/8” phone jack for external input may be present on single-phase versions.

### Physical Characteristics

* **Form Factor:** Plug-in Module

### Compatibility

* **Designed For:** Elgar AC Power Sources. The 441V is a specific oscillator module, implying it is intended to work with compatible Elgar AC power source mainframes or units. The model number system indicates that the “4” in 441V denotes a frequency range, and the “1” indicates single-phase capability.

### Manufacturer Information

* **Manufacturer:** Elgar (a division of AMETEK)

### Documentation

* **Manuals:** Service, operation, and instruction manuals for Elgar products, including the 400 Series and specific models like the 441-.155 and 441-.01SS, are available.
