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
 Do not modify.
 Do not touch the internal components, they may have high voltage or high temperature. You may get
electrical shock or burned.
 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.
 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.
 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 but there is no possibility of fire or burning.
 Confirm connections to input/output terminals are correct as indicated in the instruction manual.
 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 GWS series products, indicates compliance with the Low Voltage Directive
(2014/35/EU) in that it complies with EN60950-1 2

CN201 Connector Pin Configuration and Function Pin No. Configuration Function +Output Voltage Monitor +Sensing -Output Voltage Monitor -Sensing DCOK DCOK signal is an open collector output signal, referenced to pin6 (COM). As the output voltage drops, DCOK signal will output “High”.
  • Page 4 TDK-Lambda Series INSTRUCTION MANUAL 2-3. Basic Connection (Local sensing) Connect “+S” terminal to “+Vm” terminal with sensing wire Connect “-S” terminal to “-Vm” terminal with sensing wire Connect “CNT+” terminal to “CNT-” terminal with wire  Please use attached connector for each connection.
  • Page 5 TDK-Lambda Series INSTRUCTION MANUAL 3. Terminal Connection Method Please pay extra attention to the wiring. Incorrect connection may cause damage the power supply.  When connecting input, output wiring, and CN201, input AC-Line should be OFF.  The output load line and input line shall be separated to improve noise immunity.
  • Page 6 Input voltage which is out of specification, may damage the unit. For cases where conformance to various safety specifications (UL,CSA,EN) are required, input voltage range will be 100~240VAC (50/60Hz). Note: GWS500 series is able to withstand Input Surge of 300VAC for 5 seconds. 4-2. Output Voltage Range V.ADJ trimmer is for output voltage adjustment within the range of specifications.
  • Page 7 TDK-Lambda Series INSTRUCTION MANUAL 4-6. Low Output Detection Circuit (DCOK) Low output voltage detection circuit is provided. DCOK signal is only valid after AC input is turn-on for more than one sec. DCOK signal will turn “High” level to indicate abnormal status when the output voltage becomes less than approximately 80% of rated.
  • Page 8: Output Ripple & Noise

    TDK-Lambda Series INSTRUCTION MANUAL 4-8. Output Ripple & Noise Ripple & noise are measured at 20MHz by using a 300mm twisted pair of load wires terminated with a 0.1uF film capacitor & 47uF electrolytic capacitor. When load lines are longer, ripple becomes larger. The output ripple cannot be measured accurately if the probe ground lead of oscilloscope is too long.
  • Page 9 TDK-Lambda Series INSTRUCTION MANUAL 4-11. Output Voltage External Control (PV) Output voltage external control function is available. Output voltage can be varied by applying an external voltage (3–6V) to “PV” terminal and “COM” terminal. Please consider the following characteristics. Connection method...
