12 = 10.2 Vdc to 13.8 Vdc

The ultra-wide output voltage trim range offers major advantages to users who

select the SMT20C series. It is no longer necessary to purchase a variety of

modules in order to cover different output voltages. The output voltage can be

trimmed in a range of 0.9 Vdc to 5.0 Vdc. When the SMT20C series converter

leaves the factory the output has been adjusted to the default voltage of 0.9 V.

Output Voltage Adjustment of the SMT20C Series

J = Pb-free (RoHS 6/6 compliant)

Rated Output Current

20 = 20 A

Notes

1

Measured as per recommended set-up. 2 x Cin = 270 μF (20 mW ESR max,

Cout = 680 μF (10 mW ESR max).

2

di/dt = 10 A/μs, Vin = Nom, Tc = 25 °C, load change = 0.50 lo max. to 0.75 lo

max. and 0.75 lo max. to 0.50 lo max. At 12 V, 0.9 Vout, the max voltage

deviation is 200 mV.

3

External input fusing is recommended.

4

Measured with external filter. See Application Note 169 for details.

5

Uses external resistor from trim pin to output ground. Min value = 485 W for

5 V model, 280 W for 12 V model. See Application Note 169 for details.

6

Signal line assumed <3 m in length.

7

This product is only for inclusion by professional installers within other

equipment and must not be operated as a stand alone product.

8

Power-up is the time from application of dc input to Power Good enabled.

Remote ON/OFF is from ON/OFF asserted high to power good enabled.

9

See Application Note 169 for operation above 50 °C.

10 See Application Note 169 for ripple current requirements.

11 These models have a wide trim output. 5 Vin has an output of 0.9Vdc to 3.3

Vdc and 12 Vin has an output of 0.9 Vdc to 5 Vdc. An external resistor adjusts

the output voltage.

12 TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special

request, please contact your local sales representative for details.

13 NOTICE: Some models do not support all options. Please contact your local

Artesyn representative or use the on-line model number search tool at
