Other Details

We supply, switched-mode power supply (smps) (smps 12v @ 1a) is an electronic power supply unit (psu) that incorporates a switching regulator. While a linear regulator maintains the desired output voltage by dissipating excess power in a pass power transistor, the smps rapidly switches a power transistor between saturation (full on) and cutoff (completely off) with a variable duty cycle whose average is the desired output voltage. the salient features are enlisted below:

• input: 170 to 265 vac ; 47 - 53 hz 

• output: 12 v @ 1 a 

• size: 102 mm x 56 mm x 32 mm (lxbxh) 

• line and load regulation:

• ripple < 1 %, efficiency >70 % at full load and normal i /p 

• operating temperature: 0 to 50 deg c ; rh 95 % non condensing 

• input / output isolation > 1 kv rms @50 hz for 1 minute. 

Other features: 

• over temperature protection 

• output short circuit protection 

• output over voltage protection 

• input emi - rfi filters 

• screw type input / output connectors 

• output led indication 

• integrated mosfet and pwm controllers for greater reliability and space saving 

• 12v / 1 a and 5 v / 500 ma (both regulated) models also available
