The MPU50 Series of 50W AC/DC external power supplies have been introduced by Power Sources Unlimited. The device is very small and measures only 5.75″ x 2.99″ x 1.69″.

Its features are: safety ground leakage current of 0.1mA at 240VAC, 83% efficiency, the operating temperature of 0C to 70C.

The devices are available in single, dual and triple output models and have a 90-264VAC input. The load regulation is 0.5% and 3%, respectively.

The AEP-1500 Series of 1500W Pure Sine Wave Inverters have been introduced by Schaefer, Inc. The devices are very efficient and are designed for better AC equipment performance.

Their input ranges from 12VDC, 24VDC to 48VDC. The outputs are 115VAC or 230VAC.

The operating temperature of all models are from -30 degrees C to +60 degrees. Other features are: a digital monitor showing overload and low battery, voltage, amperage, temperature and power.

The 1500W applications are: satellite, computer, marine and general backup.

These mini-modules by Acopian offer high performance, are very reliable and made with compact design. These devices have the thermal barrier running through the power supply which isolates the hot running components from the more sensitive components.

The applications are: controls, test equipment, aviation. There is no need of sockets or soldering as the AC-DC has terminal strip input/output connections. The input voltage is 105-125 VAC, 47 to 420 Hz. The storage temperature is -55 to +85 degrees C, whereas the operating temperature: -20 to +71 degrees.

Series of 15W and 30W encapsulated AC/DC power supply modules have been introduced by Power Sources Unlimited. The devices feature universal input and approvals to EN60950-1 and EN60601-1. The applications are for OEM,  industrial and medical equipment.

The devices are available in chassis mount with screw terminals, PCB with solder pins and a DIN rail mount adaptor kit.

The operating temperature is from -25 degrees C to + 50 degrees. The power supplies are highly efficient, have protection circuitry and a 3-year warranty permit.
