Full range converters

When switchmode power supplies were introduced they could handle 110 to 240 V without the need to operate a switch or change a link. The evolving need for power factor correction facilitated 'full range' at high power.

A cost penalty was accepted by users who recognised the advantages. Today almost all power supplies available will operate on AC power anywhere in the world without intervention.

The move to full range in DC-DC converters has only just arrived.

Statronics has released a range of converters with an input range of over 10:1.

To accommodate the power standards that apply in the railway industry for rolling stock, a maximum input voltage of 200 was needed. To comfortably handle a 24 V battery and some input wiring and distribution losses, the converters perform with full performance to a minimum input voltage of 17.5 V. Even more flexibility was given to the 100 W standard model E100D12, its output being easily user-configured for 12 or 24 V or ±12 (all adjustable 11.5-14.5 V).
