Transient recovery time is measured to within 1% error band for a step change in output load of 50% to 100% Ripple & Noise measurement bandwidth is 0-20MHz. These power converters require a minimum output loading to maintain specified regulation, operation under no-load conditions will not damage these modules; however they may not meet all specifications listed. All DC/DC converters should be externally fused at the front end for protection. Specifications subject to change without notice.
