 After extensive testing, the compact NV-175 and NV-350 families of configurable power supplies from Lambda Americas , San Diego CA, a unit of TDK Corp., Tokyo, Japan, now comply with the US military’s stringent MIL-STD-810E standards for shock, transit drop, bench handling, basic transportation and shipboard vibration.
The tests, which included subjecting regular production units to 40G for shocks, are designed to simulate the exposure of units to the demanding conditions of a military environment, Lambda says. Other tests included a 1.2-meter drop test on 26 faces, corners and edges of the power supply and a vibration sweep test of 10 cycles between 10 and 500Hz. Following the tests, each unit was visually, mechanically and functionally inspected and found to be in full working order.
 NV-175 supplies are available with a choice of one to four outputs and come in the industry-standard 3×5-inch footprint. Cover and internal fan options can also be supplied. NV-350 units can be delivered with up to six outputs and are suitable for mounting in a 1U chassis.
Lambda says its NV models are CE marked in accordance with the LVD (Low Voltage Directive) and carry a host of environmental and safety agency approvals, including RoHS compliance, EN55022 Class B, UL60950-1, CSA22.2 No.60950-1, EN60950-1, IEC60950-1, EN61010-1 and EN60601-1.
