IT7300 series sets up the new standard for high performance AC power source. It equips with all powerful features such as power line disturbance (PLD) simulation, Dimmer, Sweep and comprehensive measurement functions.IT7300 series has built-in LAN/RS232/USB/GPIB communication interface(IT7321 does not have GPIB). These features make the IT7300 series ideal for commercial, power electronics and military test applications from bench-top testing to mass production. 
TRIAC Dimmer simulation function 
ITECH is the pioneer of TRIAC Dimmer function. This function is used to do dimming and speed regulating test for lamp or electric motor to ensure the products work well when controller of dimming and speed regulating is needed. 
Power line disturbance simulation function
IT7300 series provides powerful functions to simulate all kinds of power line disturbance conditions. The STEP and PULSE modes offer a method to execute a single step or continuous output changes. The LIST Mode, up to 100 sequences, extends this function for more complex waveform generator needs. In this way, IT7300 series is capable of simulating all sorts of voltage dips, surge or trapped wave. The IT7300 series enables users to perform the pre - compliance tests against IEC 61000-4-11 and compliance test against IEC 61000-4-14/-4-28 immunity test regulations.

When purchasing a power supply, the first choice to be made is linear supply or switching supply. Linear power supplies offer low ripple and noise specifications and have fast transient behavior. However they are inefficient and generate a lot of heat. They are also quite heavy. As a result most engineers prefer linear power supplies for low power applications. Using switching power supplies is a better choice for higher output power or multichannel applications. They provide higher power density. Switching power supplies are easier to control than linear supplies and cost about the same per channel.

DC output voltage slew rate is a rise or fall time. DC programmable power supplies have output filters that use large capacitors that store a lot of energy. It’s mainly the charge and discharge time of this filter, combined with the current demand of the DUT, which determine a supply’s voltage slew rate. The voltage slew rate is mostly independent of the connected EUT.

Stability is a measure of a supply’s long term output voltage or current drift. Stability is primarily specified in parts per million or ppm.

If more output current is required then paralleling power supply outputs is generally the solution. Ametek Programmable Power uses a dedicated control bus to connect its power supplies in parallel. The system configures itself automatically, identifying which unit is the master and which units are the slaves.

If more output voltage is required then connecting power supplies outputs in series is generally the solution. All you have to do is to connect the positive terminal of one supply to the negative of another. The limitation is that when operated in series, there are no master and slave units. Individual power supplies has to be programmed.

Upgrading to the Asterion power supply system has given us significant more testing capability and flexibility. It has been a wise investment. Thank you for your advice and support.

TEST LABORATORY SENIOR ANALYST AT UNIVERSITY OF NSW

Buying the MX45 California Instruments power source has given us enhanced testing capabilities. We have the SNK option, which is a bidirectional sink option. We are now able to simulate all grid conditions in our lab environment up to 45kVA. For me, reliability is important and I’m happy to say that we have been using this device for many years without any issues.

RESEARCH FELLOW AT UNIVERSITY OF WOLLONGONG

We have several Sorensen power supplies in our lab and they are the lowest output noise power supply we have experienced. For any critical research project where output noise and line/load regulations are important, we use only Sorensen power supplies.
