Elgar 1751SL AC Power Source 1.75kVA

The Elgar 1751SL is a single-phase AC power source mainframe with a power rating of 1.75 kVA. It is designed to simulate and test AC power conditions with a wide voltage and frequency range. This unit is part of the SL Series, which are solid-state linear amplifiers known for producing a clean, low-distortion sine wave output. The Elgar 1751SL is suitable for applications requiring precise and reliable AC power, such as research and development, manufacturing, and quality control environments. It is a rack-mountable unit that requires a plug-in oscillator or signal source to establish its output parameters.

### Technical Specifications

* **Model:** Elgar 1751SL
* **Power Rating:** 1.75 kVA
* **Output Voltage Ranges:** Selectable by jumper change on the rear panel. Standard ranges include 0-65 VAC, 0-130 VAC, and 0-260 VAC. Consult Elgar for other available voltage ranges.
* **Output Frequency Range:** 45 Hz to 5 kHz at full rated power. Some sources indicate a range up to 10 kHz with specific configurations or oscillators.
* **Continuous Duty:** The SL Series is designed for continuous duty at 150% of its rated capacity at 55°C into a linear resistive load.
* **Total Harmonic Distortion (THD):** Typically below 0.4% from 200 Hz to 1000 Hz, and below 0.6% over the full frequency range.
* **Line Regulation:** ±0.25% at rated load for a +10% input change at full scale output voltage.
* **Load Regulation:** ±1% from no load to full load over the full frequency range. Better than ±0.25% for fixed frequency output, adjustable to ±0.1% for specific load conditions.
* **Response Time:** Less than 2 microseconds (typical response time is <50 µsec, but specific plug-in oscillators may achieve <2 microseconds). * **AC Noise Level:** 70 dB below full output voltage with input grounded. * **Gain Stability:** ±0.25% for 24 hours at constant line, load, and temperature.### Electrical Specifications* **Input Voltage:** Selectable via rear panel jumpers for 115 VAC, 208 VAC, or 230 VAC, +10%. * **Input Frequency:** 47-63 Hz (standard for line input). * **Power Factor:** Unity to ±0.7 PF at rated VA.### Interfaces* **Signal Source Input:** Requires a plug-in oscillator or signal routing module to establish output voltage and frequency. * **Front Panel Controls:** Input power switch/circuit breaker, pilot light, and a full-range, 10-turn output voltage control potentiometer. * **Output Connections:** Available via rear panel terminal block and front panel binding posts. * **Programming:** Can be programmed via an Elgar Decoder Programmer Oscillator or other digital commands when used with a compatible plug-in programmer (e.g., PIP modules), enabling control of voltage, frequency, phase angle, and voltage dropouts.### Physical Specifications* **Form Factor:** Benchtop or 19" rackmount enclosure. * **Dimensions:** Specific height and depth vary, but some models are described as having reduced panel height, overall weight, and volume compared to previous units. * **Cooling:** Forced air cooling drawn through side panel grills and exhausted at the rear. * **Operating Temperature Range:** 0° to +55°C. (Note: One source lists -20° to +50°C for operating temperature, and -40° to +80°C for storage). * **Operating Humidity Range:** Up to 95% non-condensing.### Compatibility* **Plug-In Oscillators/Programmers:** The Elgar 1751SL is designed to work with various Elgar plug-in oscillators (e.g., Model 400 Series) and programmers (e.g., PIP modules) to define its output characteristics and enable advanced control functions. * **Multi-Phase Operation:** Multiple Elgar power sources can be stacked and driven by a multiphase plug-in oscillator to achieve multi-phase output power. * **Rack Mounting:** Designed for standard 19" rack mounting.Why Choose Aumictech for the Elgar 1751SL?
