Part Numbering Rule
ERK – 28 – S – 05 – M – 10 – P – S
ERKStandard power module, 25.4 × 12.7 × 10.8 mm
28Input voltage: 18 = 9–40 V, 28 = 16–40 V, 48 = 16–75 V
SOutputs: S = single, D = dual
05Output voltage: 3V3 = 3.3 V, 05 = 5 V, 12 = 12 V … 28 = 28 V
MTemperature grade: M = enterprise-military, −55 to +105 °C · T = industrial, −40 to +85 °C
10Output power: 10 = 10 W, 15 = 15 W
PLogic: P = positive
SMounting: S = standard, P = ruggedised
