PT 135B
NEW Empowered Model
for use with 100W digital radio
 Continuous service 22A h24
 Fan less
 No any noise emissions
 Detachable power cord, IEC socket
 Shuko plug standard, UK optional

New reliable and rugged fixed voltage 13.8Vdc power supply, linear technology, characterized by easy
maintenance, very long operative life and total absence of noise emission, recommended for any radio
communication applications, civil and professional.
Equipped with high insulation trafo 35A max, it is developed and empowered to allow continuous
service h24 22A and 25-28A for many hours (typical situation in mostly Ham Radio stations).
Compact size and strong hardware are joined to elegant and smart design with new black colour and
white lettering.
Great performances:
• Very low ripple
• High stability to load
• Blower less for very silent operating
• Overload and short circuit protection
• Over voltage protection over 15V
• Excellent immunity against lightning damage
