Closed-case Calibration 
With the ePower line, you’ll never have to send your switch mode power supply back to the factory for calibration or remove dozens of screws to reach a potentiometer.  Simply follow the AMREL calibration routine using the front panel and you should be back up and running in a very short period of time (some electronic test equipment needed).   This willvirtually eliminate downtime and eradicate the annual cost associated with shipping your power supply back to the factory for calibration.

Limit Protection
The SPD series of dual channel dc switch mode power supplies offers limit protection for over-voltage, over-current, and over-temperature.  During an over-limit condition the output is shut down instantly to protect both the unit under power and the switch mode power supply.

Full Front Panel Control 
AMREL’s dual channel switch mode power supply provides full front panel control of all available features.  A multi-function keypad allows the user to access all settings via an easy-to-understand menu system.  A LCD is provided for displaying important functions and readings.

RS-232 and GPIB IEEE-488 and RS-485 Standard 
The RS-232, GPIB IEEE-488, RS-485 and Ethernet interfaces are standard on all SPD programmable dual channel switch mode power supplies.  Connectors are provided on the rear of the unit. Instructions for configuring are in the manual.

Ethernet Optional 
The PDS series is also available with an optional Ethernet interface.

Customized Switch Mode Power Supply
AMREL’s outstanding engineering team can provide customizations and modifications to any of the SPD dual channel switch mode power supplies.  AMREL’s customizations can range from a simple modification, such as a different front panel color, to a complete custom electro-mechanical design.  Contact the factory or your local regional salesperson for more information on the customization of your switch mode power supply.
