Power Supply
Verfasst: Mi 3. Okt 2012, 09:20
Power Supply is needed for
external voltage range: 6V ...24V, e.g. lead battery 12V or solar panel (open circuit voltage up to 24V)
internal voltage: 5V DC
current: >= 0,5A
use as internal power supply:
Rohm, Bp5220a, Sip9, 1A, 8V-38V, 5,58 Euro, http://www.voelkner.de/products/270283/ ... -Sip9.html,
Recom, R-785.0-0.5 Sip3, SIP3, 0,5A, 6,5V-34V, 7,57 Euro, http://www.voelkner.de/products/82214/D ... -Sip3.html
Recom, R-785.0-1.0 Sip3, SIP3, 1,0A, 6,5V-18V, 8,32 Euro, http://www.voelkner.de/products/82218/D ... -Sip3.html
Recom, R-78b5.0-1.0, SIP3, 1,0A, 6,5V-34V, 10,00 Euro, http://www.voelkner.de/products/82224/D ... 0-1.0.html
use as internal Charge Circuit:
Microchip, MCP73831T-2ACI/OT, 738-6360, SOT-23, 3,75V...6V, 0,82 Euro, https://de.rs-online.com/web/p/batterie ... s/7386360/
Use as (external) Charge Circuit?
(for 10...20Ah Li-Ion, charge from external power supply)
