THE ENABLING TECHNOLOGY FOR INDUSTRY 4.0


NVTS are from Analytic Systems, a Canadian manufacturer of battery char gers, voltage converters, invert- ers, power supplies, frequency con- verters, and MPPT solar charge con- trollers. Founded in 1976, the compa- ny was the first to develop high-fre- quency switching voltage converters for the marine industry. Although the company still of-


fers analog converters, the emphasis and focus has been on its new “intel- ligent” digital offerings. By using its free Power Wizard software, compa- nies such as NVTS are able to define the output frequency, output voltage, output frequency and low-voltage shutdown parameters of any convert- er from a laptop with a standard micro-USB interface. In one specific recent example,


the flexibility of the power supply al- lowed the infrared camera to be used on a vessel located in Southeast Asia where the AC power source is 220 VAC. A built-in auto-sensing capabil- ity allows the intelligent power sup- ply to handle universal voltages. Another appeal of the converter,

says Janson, is that it produces a pure sine wave for cleaner utility- grade power than cheaper, quasi- sine wave alternatives. Pure sine wave inverters are ideal when oper- ating sensitive electronic devices that require a high-quality waveform with little harmonic distortion. NVTS also uses the powerful


monitoring and reporting capabilities available from DSP-based models to accommodate for voltage drops along long cable runs that, in some cases, can extend a 100 ft (30.5m) or more and involve several power supplies. In these cases, the company at- taches the cameras and digital power

fore we ship it and actually match it,” says Janson. “With the digital inter- face, we are able to physically moni- tor the actual output of the power supply using the appropriate length of cable.”


Given that NVTS’ products are


often utilized by the Coast Guard, Navy and the Department of Home- land Security, its products are con- trolled under the International Traf- fic in Arms Regulations (ITAR). As a Controlled Goods Certified facility, Analytic Systems also meets those requirements. Regardless of the type of con-


verter or electronics powered, this new breed of intelligent power con- verter and the flexibility and ease of programming will allow engineers to select from a simplified list of models and essentially receive a custom so- lution. This not only eliminates the need for application-specific designs, but also enables faster delivery of the power converter at a more economi- cal cost.
