Beta Dyne Intros AD35 Series DC-DC Converters

Beta Dyne Inc. (Bridgewater, MA) introduced its AD35 Series of 35 W high-voltage, isolated, adjustable dc-dc converters, which combine low noise and adjustability for applications that require a versatile and flexible power source. Building on its ARG3000 and SRAD20 adjustable dc-dc converters, the AD35 Series consists of four models that accept input voltages of 12 Vin, 24 Vin, 48 Vin and 110 Vin, and provide an adjustable output that can be configured as either positive (0 Vdc to +200 Vdc), negative (0 Vdc to -200 Vdc) or dual (0 Vdc to ±100 Vdc).

Based on two patents for power amplifier technology, the AD35 employs dual, low dropout linear regulators that result in reduced output noise of less than 10 mV. The AD35 Series is suitable for military, aerospace, medical and telecommunications applications. The AD35 Series features up to 88% efficiency, 2:1 input voltage range, single and dual outputs, soft start, short-circuit protection, thermal protection, 750 µA off-state current, 500 mV dropout linear regulators, dual-output tracking linear regulator, and six-sided shielding.

The converters come packaged in a coated 3.0 in x 2.5 in x 0.5 in, 30-mil copper case that allows for operation without derating or a heatsink up to 71 °C. The standard operating temperature range is -40 °C to +71 °C; optional versions with an extended operating temperature range of -55 °C to +85 °C are also available.

Pricing for the AD35 Series starts at $169.00 each, with discounts available for larger quantities. Units are available in four to six weeks ARO.
