The Emerson / Artesyn / Astec AA19920 is an AC-to-DC power supply unit designed for reliable conversion of mains power to the DC voltages required by electronic equipment. It offers robust protection features, including overvoltage, overcurrent, and short-circuit protection, ensuring stable operation in demanding environments. This power supply is suited for industrial, telecommunications, and other critical applications.
**Electrical Specifications**
* **Input Voltage Range:** 85 – 264 VAC (nominal 100-240V), or 120 to 300 VDC. For the “Emerson 20 Amp Power Supply” (which may be a related model), the input is AC 100-240V, 5.6A, 50/60Hz.
* **Input Current:** 1.77 A at 85 V AC.
* **AC Efficiency:**
* > 93% typ.
* > 92% typ.
* > 86.5% typ.
* For the Artesyn iMP series, efficiency can be as high as 91% typical at full load with 180 to 264 Vac input.
* **AC Losses:** 67 W typ., 38 W typ., 24 W typ..
* **Power Factor:** 0.53 to 0.63 across various load levels at 121.6 VAC input. Artesyn iMP series has a typical power factor of 0.99 with active power factor correction.
* **AC Input Protection:** Internally fused, non-replaceable fuses. Note: Internal fuse is for internal fault condition only. Shorts and overload will not cause the fuse to fail.
* **Output Current Rating:** Load test data indicates continuous ratings up to 6A and intermittent ratings are not specified.
**DC Output Characteristics (from load test data):**
* **Output Voltage (Under Load):** Approximately 13.75V to 14.18V across load currents from 0A to 6A.
* **Output Power (Under Load):** Up to 82.5 Watts at 6A load.
**Interfaces**
* **Field Wiring Terminals:** Includes terminals for AC Line (L1, L2), Ground (GR), DC Output (+, -), and a discrete input (DI) for monitoring power supply status.
**Physical Specifications**
* **Dimensions:**
* 119 mm H by 67 mm W by 157 mm L (4.7 in H by 2.6 in W by 6.2 in L) overall, including mounting flanges.
* Mounting holes are 148 mm (5.81 in) center-to-center.
* **Weight:** Not specified.
**Environmental Specifications**

* **Storage Temperature:** -40 to +85°C.
* **Relative Humidity:** 5 to 95%, non-condensing.
* **Protection Rating:** IP20.
* **Airborne Contaminants:** ISA-S71.04-1985 airborne contaminants class G3, Conformal coating.
* **Shock:** 10(g) RMS, three axes, 11ms for each axis.
* **Vibration:** 2.5(g) RMS, 10-2000 Hz (random); three axes for 20 minutes each – IEC 60068-2-6.
**Compatibility**
* **Associated Equipment:** The AA19920 is also known as the Motorola AA19920 Power Supply and is associated with the Motorola WPLN4171A Multi-Unit Battery Charger. It is also referenced in documentation for Emerson’s ROC and FloBoss devices, serving to power these devices and their accessories.
**Protection Features**
* Overvoltage Protection (OVP)
* Overcurrent Protection (OCP)
* Over Power Protection (OPP)
* Output current limiting and foldback protection.
* Temperature compensation of output voltage when charging batteries, with a remote-mountable thermistor.
