Connection Notes:

Typical Connection: DC Input

1. Input ﬁlter components (C¹, L1 & C2) are

used to help meet the conducted emissions

requirements (EN 55022 B) for the unit.

Recommended values are:

MicroPower Direct

292 Page Street

Suite D

Stoughton, MA 02072

USA

C²- 2.2 µF

L¹- 1.25 mH

C³- 1.0 µF

Other components added to the circuit

include an input storage capacitor to help

prevent problems due to input line sags and

an output capacitor to improve performance.

Recommended values are:

C¹- 470 µF

C⁴- 1.0 µF

T: (781) 344-8226

F: (781) 344-8481

E: sales@micropowerdirect.com

W: www.micropowerdirect.com

Typical Connection: AC Input

2. To comply with EN61000-4-5, a TVS should

be installed before the input ﬁlter compo-

nents. A SMCG51 is recommended.
