Instruction Manual

BEFORE USING THE POWER SUPPLY UNIT

Pay attention to all warnings and cautions before using the unit. Incorrect usage could lead to an electrical

shock, damage to the unit or a fire hazard.

WARNING and CAUTION

z Do not modify.

z Do not touch the internal components, they may have high voltage or high temperature. You may get

electrical shock or burned.

z When the unit is operating, keep your hands and face away from it as you may be injured by flying debris in

the event of a fault.

z This power supply is designed for use within an end product. Stick the WARNING label for users on the

system equipment and notify in the system instruction manual.

z Never operate the unit under over current or short-circuit conditions for more than 30 seconds or outside its

specified Input Voltage Range, which could result in damage. There is no possibility of fire or burning.

z Confirm connections to input/output terminals are correct as indicated in the instruction manual.

z This power supply has a possibility for hazardous voltage to appear at output terminal depending on the type

of failure. The outputs of these products must be earthed in the end equipment to maintain SELV.

If the outputs are not earthed, they must be considered hazardous and must not be made user accessible.

Note: CE MARKING

CE marking, when applied to the LS series products, indicates compliance with the Low Voltage Directive

(2006/95/EC) in that it complies with EN60950-1

TDK-Lambda LS 25-150 Series INSTRUCTION MANUAL 3. Explanation of Functions and Precautions 3-1. Input Voltage Range Input voltage range is single phase 88 ~ 264VAC (47 ~ 63Hz) or 125 ~ 373VDC for LS25 ~ LS100. For LS150, selectable switch 115/230VAC will decide the input voltage range as mentioned in the table below. Input voltage which is out of specification, may damage the unit. For cases where conformance to various safety specs(UL,CSA,EN) are required, input voltage range will be 100~240VAC (50/60Hz ).
