6400 series

The 6400 Series Programmable AC Power Sources uses state of the art PWM technology to deliver pure, instrument grade AC power at very low cost ever achieved before. The 6400 AC power source offers maximum rated power for the output voltage from 0V to 300VAC, at the frequency from 45Hz to 1kHz. It is not only suitable for commercial applications (47Hz - 63Hz), but also for avionics, marine, and military applications at 400 Hz.
The 6400 Series Programmable AC Power Source generates very clean output with typical distortions less than 0.3%. With the incorporated of power factor correction circuit, the 6400 AC Power Source yields higher efficiency and delivers more output power than competitive instruments. Furthermore, it is capable of providing high peak repetitive current that is required to drive most electronic products with high crest factor input design.
The 6400 Series AC Power Source uses advanced DSP circuit to offer precision and high speed measurement for true RMS voltage, true RMS current, true power, frequency, power factor, and current crest factor.
The 6400 AC Power Source is very easy to operate through the front panel keypad, or the remote controller via IEEE488. RS-232C or APG (Analog Programming) interface. The optional interface is designed as a plug-in card to change the unit in seconds into a computer controlled system power source.
Designed with self-diagnostic, routine and protections against over voltage, under voltage, overpower,over current, over temperature and fan fail. The instrument has the qualities and reliability that can suit for the most demanding applications in production, test, R&D design, and QA verification.

The Cost Effective Programmable AC Power Source
The 6400 Series AC Power Source supplies very clean output with typical output distortion less than 0.3% THD. The output is transformer isolated (6404&6408) providing an exceptionally low total harmonic distortion without sacrificing efficiency. Remote sense connections are provided for superb output regulation to compensate for load line losses while keeping the output a precise level regardless of output load condition.
The 6400 Series incorporates input power factor correction circuitry resulting in high effiency and lower input line current. The 6400 Series employs advanced DSP circuitry (6404&6408) or 16-bit measurement circuit to provide precise high-speed measurement of the output for true RMS voltage, true RMS current, true power, frequency, power factor, and current crest factor. These output measurements can be displayed on the large, easy to read, front panel readout. The 6400 Series are easy to operated using the front panel keypad, (6404&6408) with 9-user programmable output voltage, frequency, and current limit combinations for quick and consistent testing. An optional controller can be added for GPIB/IEEE-488, RS232C, or analog programming for completely automated testing applications. The interface is a plug-in card that can change the 6400 from a manual unit to a computer-controlled system AC power source.
With the small 13.5 cm height packages (6404&6408), and lightweight, the model 6400 is perfectly suitable for bench top applications where space is at a premium. The easy to use and easy to read front panel control/readout system makes setup and quick measurements simple. The front panel receptacles can be used for most line cord plugs without adapter. Rear panel terminals are also provided for hard-wired connections. A temperature controlled fan speed circuit is used to keep fan noise reduced when operating on the bench or in a quiet lag environment. The 6400 Series can also be easily rack-mounted without special mounting kits or modifications.
The wide output voltage range of 0-300VAC (0-500VAC for Model 6460) can be selected for either 0-150VAC or 0-300VAC, or set to auto-ranging output voltage. The 45-1000Hz output frequency range provides excellent flexibility in a small compact unit with a great performance/low ratio. The programmable current limit adds the flexibility while reducing current flow potential for non-destructive test easily.
The 6400 Series provides a self-diagnostic routine, easy to set programmable output over voltage limit, input line under voltage protection, output over power, over current, over temperature, and fan failure protection.
The 6400 Series offers quality, reliability, and flexibility for the most demanding applications in production tests, R&D, and QU verification.
