Conformity to RoHS Directive
AC Input
Single Output, General-Purpose, UL/C-UL/TÜV Approved
R Series RTW(50 to 300W)
This is an ultra-thin, high-performance standard power supply that is both energy efficient and environmentally friendly. Utilizing TDK’s
unique material, mounting, noise reduction and thermal analysis simulation technologies, these products have been reduced by 50% and
60% in volume and weight respectively compared to existing TDK products. All components are lead-free and compatible with the envi-
ronmental assessment program.
FEATURES
• Conforms to EN61000E-3-2 regulations for high harmonic cur-
rents.
• Wide input (AC.100-200) No toggling required.
• Conforms to EMS standards EN61000-4-2, 3, 4, 5, 6, 8 and 11.
• Conforms to FCC-B and VCCI-B regulations for radiating and
transmission noise.
• CE certified.
• Approved by safety standards (UL, C-UL and TÜV). Conforms to
the Electrical Appliance and Material Safety Law (Compliant with
creepage surface and air clearance in Attachment 8).
• 5-year limited warrantee.
• Life span of electrolytic capacitor: 60,000hours or more.
• Lead-free.
• Does not use designated bromine flameproof material (PBPEs
and PBBs).

• Available in 1U and 2U rack sizes.
These are particularly suited for situations that call for thin prod-
ucts. They are designed so that they can be attached on both
sides.
• The remote control feature (which was optional in previous prod-
ucts) is now standard and can be used by toggling an internal
switch.
• It is a product conforming to RoHS directive.
APPLICATIONS
• Semiconductor fabrication equipment
• LED displays
• Wire and wireless communication equipment
