- NF-Programmable AC/DC Power Source EC750SA / EC1000SA
The Hybrid Power Control Achieves Stable Output in Various Load Conditions! For R&D, Production Lines, Built-in ATE System
The EC750SA and EC1000SA provide not only a stable power supply, but also the necessary functions for power supply testing, such as measurement, current limiter, , and sequence functions.
They covers various applications as a power source for testing a wide range of fields, such as electronic components, automobiles, and home appliances, and as a stabilized power source in laboratories as well.
Programmable AC/DC Power Source
Model:
EC750SA / EC1000SA
Maker:
NF Corporation
Features
The hybrid power contol integrates the negative feedback control (analog control technology), which is NF’s core technology, and intelligent digital control technology.
Analog technology is provided when wide-band, high response is required, and digital technology is provided for flexible control according to load condition.
The hybrid power control achieves highly stable and robust output by taking full advantage of both analog and digital characteristics.
A Variety of Outputs
With AC, full-power output is also available for DC. In the AC+DC mode, an AC wave (sine wave, square wave, or arbitrary waveform) can be super- imposed on the DC output.
Operation mode
Eight output modes, combining two operation modes and four signal source modes can be set. The most appropriate mode for an application can be selected.
Maximum output peak current
A peak current up to four times as large as the maximum current (RMS values) can be output at the rated output voltage. The EC series also supports capacitor input load (up to crest factor 4).
Limiter function
Output current limits can be set with positive/negative values, and RMS values. In the evaluation of a prototype, this function is useful for protection when an abnormal current is caused by abnormal operation of the load.
Protection function
The EC series has a built-in function for protecting the power source itself if a problem occurs due to issues such as output overvoltage or overcurrent, power unit trouble, internal control problems. If a problem occurs, it is displayed on the panel and output is turned off.
Examples of use
- LED Drive Input Voltage Test support for LED driver input voltage of AC 90V to 305V (Worldwide specifications)
- AC+DC mode Evaluation of DC-DC converter. For Noise superimposition test and ripple current test
- DC Offset Adjustment Driving Transformers and Inductive Loads. Prevention of magnetic saturation by adjusting DC offset voltage to zero
