AC/DC Power Modules TMSB 2 Series, 2 Watt CB Scheme LVD UL 60950-1 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 LEDs Constant voltage auxiliary outputs 3.3 and 5 VDC Operating temperature range 30C to +70C EMI meets EN 55022, class B and FCC, level B Short circuit and overload protection 3-year product warranty 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, LEDs 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 85264 VAC, safety approvals including approvals for household applications (EN 60335-1) and an operating temp. range from 30C to +70C qualify them for worldwide markets.
