ESCRIPTIONS
The 1600XA series 16 watts high performance DC/DC
converters are cost effective solution to the high reliability
and performance requirements of power distribution
systems in applications ranging from high speed data
communications equipment to industrial robotic systems.
The 1600XA series operates from wide (2:1) input voltage
ranges of 9 to 18, 18 to 36 or 36 to 72VDC; providing single,
dual and triple output combinations of 5, 12, 15, ±5, ±12, ±15,
5/±12 and 5/±15 VDC. All models are packaged in compact,
low profile 2” X 2” X 0.4” metal cases.

Ordering Information:
1. Case “A” pinning is standard. Models with Case “A”
packaging do not require a suffix on the part number.
2. Case “A1” is an alternate. Models with Case “A1”
packaging must be designated with an “A1” suffix;
e.g. 1615D48XA-A1.
