Catalog Number

SM2

SM3

Input

Less than 20 A peak

Less than 40 A peak

Compliant with EN61000-4-2, 3, 4, 6 (Level 3 minimum)

Output

Less than 0.1% for line variations from 90-264 VAC.
Less than 0.3% for dual and triple output modules. 

Less than 1.0% no load to full load. 
Less than 2% for dual and triple output modules. 

Less than 0.1% between single output modules.
Less than 2% between dual outputs with 25% step load change on main output. 

Single wire on all main outputs, droop on secondary outputs.

±10% of nominal on all main outputs 5-15 volts on
U and T module Auxilliary outputs

OVP is standard on all main output modules and low voltage secondary outputs. 120-130% of nominal.

OVP is standard on all main output modules and low voltage secondary outputs. 115-130% of nominal.

No preload is required on any single, dual output module. A min 1A, max 10% preload is required on main output of triple and slim-line dual (U) outputs in order to achieve specified regulation.

 ±25% load change from a steady state 75% of nominal at a rate of 1A/msec will result in an output deviation no greater than 2% or 100 mV peak. 125 mV for outputs 4V or less. Outputs are to recover to within 1% of nominal voltage within 350 msec.

General

75% typical at nominal line

 0.02 - 0.03%/^°C

 All AC Input units will maintain regulation within specifications for a period of not less than 16 msec for 60 Hz, (20 msec for 50 Hz) at full rated load from nominal 230 line voltage.

All single output, main output on triple outputs and dual output "D" modules incorporate remote sense and are able
to compensate for a total cable drop up 
to 0.5 VDC. Dual output "G" modules 
do not have remote sense. 

Temperature performance curves are available. Contact Technical Services.
