* Any one phase or neutral can be grounded
* Selectable 1 or 3 Phase Output (Option MODE on 1503L-3P)
* **Output Frequency Range:**
* 45 Hz to 5 kHz
* 17 Hz to 5 kHz (for 1503L-3P)
* **Frequency Control:**
* Controlled by an Elgar three-phase plug-in oscillator
* Available in variable frequency or fixed frequencies
* Accuracy up to 0.0001%
* Fixed oscillator example: 400 Hz, 3 Phase, 0.1% Tolerance
* **Power Factor:** Unity to ± 0.7
* **Line Regulation:** ±1 volt (reported in context of 150kVA, may vary with actual configuration)
* **Load Regulation:** (Specifications vary based on load and frequency, adjustable through zero)
* **Distortion:** (Not explicitly detailed in the provided snippets)
* **Hum and Noise:** (Not explicitly detailed in the provided snippets)
* **Input Power:** (Not explicitly detailed in the provided snippets)
* **Internal Architecture:**
* Functionally consists of two DC power supplies, three power amplifiers with associated control circuitry, and a three-phase output power transformer
* DC supplies are obtained from a full-wave bridge rectifier on the secondary of the input power transformer, nominal ±45V DC
* Three power amplifiers mounted on heatsink assemblies, controlled by plug-in amplifier circuit boards
* Uses a triple-phase diode rectifier bridge
* Features a simple design with two main circuit boards
* **Control and Monitoring:**
* Front panel amplitude control potentiometer
* Digital microprocessor controls variable power output, provides diagnostic monitoring and protection
* Electronic programming features: voltage and current control, voltage and current monitoring, overload reduction
* Programmable Controller Module installed (on 1503L-3P)
* Automatic remote calibration and comprehensive self-tests (L Series)
### Electrical Characteristics
* **Input Voltage:** 115/230 VAC (for 1503L-3P)
* **Input Phase:** 1-Phase (for 1503L-3P)
* **Input Frequency:** 47-440 Hz (for 1503L-3P)
### Interfaces
* **Output Connections:**
* Front panel binding posts
* Rear panel output power terminal block
### Physical Characteristics
* **Enclosure:** High-grade aluminum alloy, designed for noise-cancelling and heat dissipation, resistant to wear and tear
