AC/DC Power Modules

TMSB 2 Series, 2 Watt

The TMSB-2 series are compact AC/DC power supplies in a fully encapsulated

plastic casing with solder pins for direct PCB mounting. They feature regulated

outputs and constant power characteristics which make them suitable to drive relays,

solenoids, LED’s and capacitive loads. Models with an additional regulated

auxiliary output can be used to power a logic circuit in standby functions.

An universal input voltage 85–264 VAC, safety approvals including approvals for

household applications (EN 60335-1) and an operating temp. range from –30°C to

+70°C qualify them for worldwide markets.

Features

◆ Standby power module to comply

with ErP directive

◆ No load input power < 150mW

◆ Constant power characteristics at 2W

(no current limitation)

◆ Suitable to drive relays, selenoids,

capacitive loads and LED’s

◆ Constant voltage auxiliary outputs

3.3 and 5 VDC

◆ Operating temperature range

–30°C to +70°C

◆ EMI meets EN 55022, class B and

FCC, level B

◆ Short circuit and overload protection

◆ 3-year product warranty
