Elgar 1751SLE AC Power Source 1.75kVA

The Elgar 1751SLE is a single-phase AC power source designed for precision power generation in testing and laboratory applications. It belongs to the SL Series, which are solid-state linear amplifiers known for producing low-distortion, stable sine wave power. These units are suitable for benchtop or 19″ rackmount configurations and can be driven by external oscillators for voltage and frequency control. The 1751SLE is built to meet CE mark requirements, indicating compliance with European safety and electromagnetic compatibility standards.

### Technical Specifications

**General**
* **Product Series:** SL Series
* **Type:** AC Power Source
* **Topology:** Solid-state linear amplifier
* **Harmonic Distortion:** Typically below 0.3% midband, 0.6% over the full frequency range.
* **Continuous Duty:** Capable of continuous operation at up to 150% of rated capacity into a linear resistive load.
* **Protection:** Features overload and over-temperature protection.
* **Form Factor:** Benchtop/19″ rackmount unit.
* **Compliance:** Designed to meet CE mark requirements.

**Output Characteristics**
* **Power Rating:** The 1751SLE model is rated at 1750 VA.
* **Output Voltage Ranges:** Configurable voltage ranges are available, typically including 0-65 VAC, 0-130 VAC, and 0-260 VAC. Specific output range selection is made via jumper settings on the rear panel.
* **Output Frequency Range:** Operates from 45 Hz to 5 kHz at full rated power, with an optional expansion to 10 kHz.
* **Load Regulation:** ±1% from 45 Hz to 450 Hz with a pulsed load, or from 45 Hz to 1000 Hz with a linear load.
* **Line Regulation:** ±0.25% at rated load for a ±10% input voltage variance.
* **Crest Factor:** High crest factor currents are supported, up to 6:1 for firing angles less than 10 degrees from the voltage peak.

**Interfaces and Control**
* **Programmability:** Full IEEE-488 GPIB control is available when used with an Elgar Plug-In Programmer (PIP), enabling control over voltage, frequency, phase angle, voltage dropouts, and test readback of output parameters.
* **Internal Range Change Relays:** Optional relays allow switching between voltage ranges (e.g., 130 VAC and 260 VAC) under GPIB or local front panel control when used with a PIP.

**Electrical**
* **Input Voltage:** Standard input voltages include 115 VAC, 208 VAC, and 230 VAC for single-phase operation.
* **Input Frequency:** Operates within a 47-63 Hz range, with an optional 400 Hz input available.

**Physical**
* **Dimensions:** The height for the 1751SX model (which shares similar power ratings and characteristics with the 1751SLE) is 12.25 inches.
