Single-phase 1.5kW power supplies are programmable
Claimed to offer advanced programmability in a compact package, the HPA1K5  

AC/DC power supplies offer programmable CV and CC operation with analogue and digital interfaces for user control. The compact power supplies use an efficient resonant zero-volt switching (ZVS) topology and are suitable for equipment used in a range of industries including industrial, process control, medical, semiconductor fabrication, test and measurement, printing and water treatment, advise the company.

In-built digital control allows users to rapidly configure (and re-configure) the power supply for any application using software settings rather than complex and time-consuming hardware changes, advises the company.

The power supplies measure (279.4 x 106.7 x 41.7mm (11.0 x 4.2 x 1.64 inches) to occupy less space than typical 1.5kW-rated power supplies, and represent both space and weight savings in the end application, according to XP. The power supplies up to 93% efficiency and fast slew rates for instrumentation applications.

The input range of 80 to 264V AC ensures operation in most markets worldwide and requires minimal low line derating. Nominal single output voltages of 24V DC and 48V DC are available as standard. These can be programmed up to 105% of nominal. The current output can be programmed to 110% of nominal. An additional 5V/2A standby supply is always on if the mains supply is present.

The supplies are approved to EN55011/EN55032 for EMC emissions, EN61000-4-x for EMC immunity and IEC62368-1 Ed. 2 for ITE safety. For medical applications, the units are approved to IEC60601-1 Ed. 3 (including risk management) and offer 2 x MOPP (means of patient protection) from primary to secondary.

They support multiple digital protocols including PMBus, CANopen, MODBUS and SCPI. A full duplex RS485 interface is included which can be configured to half duplex via I2C, or be factory configured. Analogue control is available via a 0 to 5.0V programming option.

A graphical user interface (GUI) and a suite of development tools are included for fine-tuning during the development phase, or reconfiguration for a different application.

Up to five units can be configured in parallel using the inbuilt current sharing technology, if required.

Suitable applications for the HPA1K5 series include medical imaging and patient treatment / diagnostics, etch and deposition in semiconductor fabrication, battery charging, robotics, and lasers. They can also be used in LED heating / curing, industrial printing, electroplating, cathodic protection, water purification and hydrogen generation.

The power supply series is available from Digi-Key, Distrelec, Farnell, Mouser, RS Components, approved regional distributors, or direct from XP Power with a three-year warranty.
