ELGAR 401CVE

The Elgar 400 Series of plug-in oscillators, including models such as the 401CVE, are designed to provide precise output frequencies for Elgar AC power sources. These oscillators are integral components that offer flexibility and optimize price-performance for specific applications. They can be utilized with Elgar Linear AC power sources to deliver variable or fixed frequencies with a low-distortion sine wave output.

### Technical Specifications

#### Oscillators (General)

* **Functionality:** Provide required output frequency for Elgar AC power sources.
* **Output Signal:** Low distortion sine wave.
* **Configurations:** Available in single, dual, or three-phase configurations.
* **Types:**
* RC Phase Shift Oscillators (Fixed or Variable): Lower cost alternative for applications not requiring crystal control accuracy; suitable for continuous sweep frequency.
* Crystal Controlled Precision Oscillators (Fixed or Variable): Offer precision frequency resolution and calibration accuracy.
* **External Programming (Optional):**
* Amplitude programmable via external resistor (e.g., 0-13 kOhms for 0-full scale output voltage).
* Amplitude programmable via external DC voltage (e.g., 0-10 VDC for 0-full scale output voltage).

#### 400 Series Fixed Frequency RC Phase Shift Oscillators

* **Operating Frequencies:** 50 Hz, 60 Hz, or 400 Hz.
* **Configuration:** Available in single, dual, or three-phase.
* **Accuracy:** ±0.1% (when ±0.1% accuracy is required).
* **Single Phase Versions:** Include a 1/8” phone jack for external input.

#### 400 SD/400 SDE Series (RC Phase Shift Oscillators)

* **Frequency Selection:** Manual selection via decade dials and range switches.
* **Frequency Range:** 45 Hz to 5 kHz.
* **Frequency Resolution:** 0.01 Hz, 0.1 Hz, or 1 Hz.
* **Calibration Accuracy:** ±0.001% of set value.
* **External Voltage Programming:** 0 to 26 VDC input for 0 to 260 V output.
* **Front Panel Features:** Frequency limit LED indicates if frequency is below 44 Hz or above 5100 Hz, causing output to drop to zero.

#### 400SP Series (Crystal Controlled Precision Oscillators)

* **Frequency Selection:** DIP switches (internal), inverted logic (off position enables bit).
* **Frequency Range:** Selectable via jumper (e.g., 45-99.99 Hz, 45-999.9 Hz, 45 Hz to 5 kHz).
* **Precision:** Frequency resolution of 0.01 Hz.
* **Calibration Accuracy:** ±0.001% (typical).
* **Amplitude Adjustment:** Adjusted by the gain potentiometer on the associated power source.

#### General AC Power Source Characteristics (Associated with Oscillators)

* **Line Regulation:** ±0.25% at full load for ±10% change in input line voltage.
* **Load Regulation:** +1% from no load to full load over the full frequency range and ±10% input range. Can be adjusted to better than 0.1% for specific load conditions.
* **Response Time:** Less than 50 µsec.
* **Noise Level:** 70 dB below full output.
* **Gain Stability:** ±0.25% for 24 hours at constant line, load, and temperature.
* **Temperature Range:**
* Operating: -20°C to +50°C.
* Storage: -40°C to +80°C.
* **Output Control:** Output-on switch.
* **Protection Features:** Overvoltage, overcurrent, and overtemperature protection.
* **Remote Sensing:** Standard.

### Interfaces

* **External Input:** 1/8” phone jack (on single-phase versions of 400 Series Fixed Frequency RC oscillators).
* **External Programming:** Via resistance or DC voltage for amplitude control.

### Physical

* **Form Factor:** Plug-in modules designed to integrate with Elgar AC power sources.
* **Mounting:** Secured by captive screws on the front panel of the power source.

### Compatibility

* Designed to function with Elgar Linear AC power sources.
* The 401CVE is a specific model designation for a variable oscillator within this series.
