Elgar 1751SX AC Power Source

The Elgar 1751SX-34TD is a high-performance AC power source engineered for comprehensive AC power condition simulation and testing. Its design caters to engineers, system integrators, and laboratories requiring precise control over voltage, frequency, and current for demanding applications. This unit is particularly well-suited for product testing, avionics applications, and the evaluation of power supplies. The 1751SX-34TD integrates a user-friendly interface with advanced features to address complex power testing requirements, including the simulation of non-linear rectifier loads common in modern switch-mode DC power supplies.

### Technical Specifications

**Output Characteristics:**
* **Power Output:** The SX series, including the 1751SX, is designed to provide 150% of its rated capacity into linear resistive loads.
* **Voltage Range:** Output voltage ranges include 0-65 VAC, 0-130 VAC, or 0-260 VAC, selectable via rear panel jumper changes. Consult Elgar for other voltage range configurations. Specific models like the 1751SX-04-208 offer relay-switched output ranges of 130V / 260V.
* **Frequency:** Operates within a frequency range of 45 Hz to 1 kHz. An optional 380-420 Hz input is also available.
* **Crest Factor:** Capable of high crest factor currents, ranging from 3.5:1, up to 6:1 for firing angles less than 10 degrees from the voltage peak. This capability allows for repetitive peak currents up to 70 amps, depending on the model, making it ideal for testing equipment that causes peak loads on AC power lines.
* **Low Harmonic Distortion:** The SL Series (related to SX series) is noted for low harmonic distortion.
* **Low Effect Output Impedance:** Features a low effective output impedance for stable power delivery.

**Input Characteristics:**
* **Input Voltage Configuration:** The 1751SX-34 Elgar AC Power Supply can be configured for 115, 208, or 230 VAC input. Some models, such as the 1751SX-04-208, require 3-phase 208VAC input power.
* **Input Frequency:** Operates at 47-63 Hz, with an optional 380-420 Hz range.

**Protective Features:**
* **Overload Protection:** Equipped with overload protection to safeguard the unit and the connected load.
* **Temperature Protection:** Features built-in temperature protection to prevent overheating.

**Advanced Features & Control:**
* **Programmability:** Can be manually or IEEE-488 (GPIB) programmed using Elgar’s Plug-in Programmers. Some models include an integrated programmable oscillator, such as the 9012A.
* **Range Change Relays:** Incorporates range change relays that allow for voltage range switching via GPIB or the front panel.
* **Non-linear Load Testing:** Specifically designed to drive non-linear rectifier loads and meet the electrical power requirements for testing modern switch-mode DC power supplies.
* **Configurable:** The SX series is configurable to meet specific testing needs.

**Physical Characteristics:**
* **Form Factor:** Increased peak power capacity and reduced package size make this series suitable for benchtop testing.

**Compatibility:**
* **Oscillator Compatibility:** Compatible with the manual 400 series oscillator, which is sold separately.

**Safety Considerations:**
* **Hazardous Voltages:** Operates with potentially hazardous voltages. Installation and servicing must be performed by qualified personnel aware of attendant hazards. Capacitors may retain a charge even when power is off. Output terminals may generate hazardous voltages, requiring proper labeling and precautions against inadvertent contact.
* **Grounding:** Proper grounding of the AC power line and other power ground lines is essential for both personnel and equipment safety.
* **Circuit Breaker:** The AC Power Source circuit breaker must be switched OFF before connecting or disconnecting power or loads.
