VTC Common Negative DC/DC Converters

The input and the output of the common negative DC/DC Converters share the same ground. These do not typically use a transformer and are less expensive to build. Models are available to step-down (Buck), step up (Boost), or a combination of step down and step up (Buck-Boost).

Step down VTC300 and VTC600 models handle up to 45VDC input, stepping down to 12 to 24VDC with power ranges of 300 and 600 watts.
Step up VTC305 and VTC605 models stabilize a 12V system, or step 12VDC up to 24VDC with power ranges of 300 to 600 watts.

Designed to perform in the harshest environments

No matter which unit you need, these easy-to-install Voltage Converters will give you many years of reliable service.

VTC Voltage Converters use efficient filtering, allowing for ultra-quiet operation. In addition, the converters are:

  • Made from marine-grade aluminium extrusions or heavy-gauge aluminium sheet metal
  • Powder-coated or anodized, and use stainless fittings throughout
  • Fitted with robust circuit boards using expensive heavy-gauge copper conductors

Features of the Common Negative VTC DC/DC Converters

  • High Performance:
    • Designed to perform in the harshest environments, the units cope with 100% continuous duty-cycle loads under wide temperature ranges. Peak currents are also  available up to 40% above rated output.
    • Voltage regulation, and precision PWM control circuitry ensures constant output voltages regardless of the load. Efficiency of more than 90% across the load range result in greater heat dissipation making the units cool-to-the-touch.
  • Rugged and Reliable:
    • Heavy-duty construction in high-grade materials. The extensive use of non-corrosive materials ensures the units can withstand harsh marine and industrial environments. The casing is made from heavy-gauge aluminum sheet metal or from extruded marine-grade aluminum. All fasteners and terminals are stainless steel. An optional protective conformal coating is available for humid environments.
  • Ultra-Quiet, Low EMI Operation:
    • Multiple stages of filtering reduce radiated and conducted noise to very low levels. Output noise levels of far less than 50mV and typical Line-Load regulations of +/- 0.5% allow all units to comply with the current US FCC and European CE Standards for Electromagnetic Compatibility (EMC).
  • Built for Safety:
    • In addition to adjustable output voltages, all Analytic Systems’ VTC Series DC Converters are fully protected by a range of built-in safety features. All units include reverse input  protection, over-temperature shutdown, current limiting, short circuit shutdown, a dry contact output fail relay output and output over-voltage crowbar. Additionally, the 300W and above models include high-visibility, visual and audible indicators to allow the monitoring of low input voltage, low output voltage, over temperature, overload and power ON-OFF.
  • Three year Warranty
    • Manufactured in North America, all VTC Series Voltage Converters comply with safety and occupational health standards and are 100% fully tested and burned-in before shipment.
    • 3 years product warranty against failures and faults.
