SynQor - AC-DC and DC-DC Power Converters for Medical Electronics

With its headquarters and manufacturing facility located in Boxborough, Massachusetts, and sales and support offices worldwide, SynQor designs and manufactures state of the art AC-DC and DC-DC power converters for medical electronics OEMs.

As the pioneer in the use of synchronous rectification and planar magnetics, which revolutionized the 48VDC DC-DC converter market-place in 1997, SynQor now offers comparable performance levels in its ACuQor and InQor (AC-DC and DC-DC respectively) medical grade power supplies.

SynQor is certified to both the ISO 9000 and ISO 13485 standards and offers 100% component and unit traceability.

ACUQOR AC-DC POWER SUPPLIES

Offering microprocessor control, high efficiency and full EN/UL 60601-1 safety compliance for patient contact type BF and type CF applications, SynQor’s ACuQor series of AC-DC power converters offers power densities second-to-none in the medical market-place.

The current sharing function enables 600W, 800W, 1kW, 900W, 1.2kW or 1.5kW of power while still meeting the type CF patient and earth leakage current levels.

Other options include defibrillator proof isolation (5,000V) on the secondary, a non-fan, and a triple output version of 24VDC, 36VDC, or 48VDC primary outputs with 12VDC at 3A and 5VDC at 2A in the same footprint as the single output version.

Key product family features and benefits are:

• 400W steady-state/500W surge in 3in x 5in x 1.4in (metric) package
• Exceptional efficiency of up to 91% means simplified cooling and high reliability
• Meets all medical requirements including BF, CF, CFD (defibrillator isolation)
• Leakage current below medical requirements, input leakage current as low as 62µA, output leakage current as low as 2µA
• Integral fan with speed control for highly varied installations
• Worldwide input voltage range of 85VAC to 264VAC, at 50Hz or 60Hz
• Semi-regulated output for stability and inherent load sharing when paralleled
• Active PFC meets international requirements (EN61000-3-2)
• Transient immunity, ESD protection, flicker meets standards (EN61000-4)
• Conducted EMI qualified to EN55011 and EN55022, FCC part 15 class B
• ISO 9000:2000 certified factory and CE mark
• Protection features: over-voltage, over-current, over-temperature
• Special control features: standby power, fan disable, fault signal, serial bus
• Multiple mechanical configurations available, see data sheets for more information

INQOR - BUCK / BOOST ISOLATED CONVERTERS

The InQor series of industrial grade buck / boost isolated converters offers a wide range of products ideal for use in battery powered applications.

This series of industrial grade isolated converters provides a number of wide input voltage ranges, with nominal 12VDC, 12VDC / 24VDC, 36VDC, 72VDC, and 110VDC in a wide variety of output power (50W-200W) and voltage (1.8VDC-48VDC) configurations.

Its buck / boost topology enables the converters to either step up or step down the output voltage which provides a constant output while battery charge is depleted.

Key product family features and benefits are:

• High power density, smaller size allows more board area and design flexibility
• High efficiency up to 95% yields lower power dissipation and requires less cooling
• Offered in 2:1, 4:1, and 8:1 input voltage ratios
• Reinforced insulation
• Fully encased ruggedized mechanical package
• Wide range of outputs from 1.8V to 48V for numerous publication requirements
• Fixed switching frequency yields predictable EMI filtering

HIGH VOLTAGE NIQOR (HVNQ) NON-ISOLATED BUCK / BOOST REGULATORS

SynQor’s non-isolated HVNQ products are a variable output non-isolated buck / boost regulators. They can be efficiently used to provide a regulated output voltage from a battery source or other variable voltage source.

They can also be configured to buck the input voltage down to a lower voltage, or boost the input voltage to a higher output voltage using a single external resistor.

Key product family features and benefits are:

• Buck stage, followed by boost stage
• Input voltages of 9VDC-20VDC, 9VDC-40VDC, 9VDC-60VDC
• Digital control
• Output voltage ranges of 0VDC-20VDC, 0VDC-40VDC, or 0VDC-60VDC
• Output currents of 5A-40A
• Output can be set to read the external programming resistor once, or to continuously read the value, so allowing for active trim
• Current mode / battery charging module available
