VPT introduces VSC series of space COTS converters

02 August 2022

VPT Inc., a HEICO company, has unveiled the VSC series of commercial off the shelf (COTS) products intended for “New Space” applications as part of its space product line. The VSC series has been characterized for Total Ionizing Dose (TID) performance including Low Dose Rate (LDR) and for Single Event Effects (SEEs) according to VPT’s Radiation Hardness Assurance (RHA) plan. The series is designed for smaller satellites in low Earth orbits (LEO), and NASA Class D missions where the balance of cost and guaranteed performance is critical.

The VSC series of DC-DC converters ranges from 5 W to 30 W of output power and includes single and dual outputs of 3.3 V, 5 V, 12 V and 15 V with a wide input range of 15 V to 50 V with 80 V transient capability. The VSC series is radiation tested to 42 MeV/mg/cm2 and guaranteed to 30 MeV/mg/cm2 for SEE and tested to 50 krad(Si) and guaranteed to 30 krad(Si) for TID. A full line of input EMI filters is available to meet MIL-STD-461 or equivalent conducted emissions requirements.

VPT’s vice president of engineering, Leonard Leslie, stated “The VSC series leverages VPT’s extensive experience in radiation hardened DC-DC converter development to provide the appropriate level of radiation performance for LEO applications at an extremely competitive price point.”

The VSC series single and dual output DC-DC converters are available for immediate sale. Sales are subject to all applicable U.S. export license restrictions and regulations.
