TDK-Lambda LS Series User manual

Compact AC/DC Switching Power Supply
LS Series

・All specifications are subject to change without notice.
LS Series are smaller than current models in which can give
more exibility in design. is compact design is ideal for
application including indoor display, self service kiosk, and
vending machines.
High eciency power output will reduce the amount of
wasted energy. Strict evaluation of components used will
also reduce defect. erefore, user's overall running cost
can be minimized.
LS series are designed to operate reliably between -25°C to
50°C at 100% load and up to 70°C at derated load. is
feature is the best solution for equipment to run in extreme
environments.
*Refer to each model specication for derating
LS series cover most of the output voltage to cater wide
range of applications. e available 36V is suitable for
applications like printer head or LED display panel.
Compact Size
Wide Operating Temperatures Low and High Voltage Full Line Up
Economical and
Environmental Friendly
A Power Supply that Protect Your Equipments
LS series are not only designed to meet the harmonic current standard (IEC61000-3-2,-3), but also to pass this
standard with enough margin so that equipments will be well protected against overheating and malfunction. In addition
to conformance to the international standards, LS series have less than 1mA leakage current and ability to withstand
300VAC surge for 5 seconds for better safety and protection.

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. Insulation failure, burning, smoke or other
damage may occur.
• 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 at 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.
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.

・All specifications are subject to change without notice.
LS Series
󱫀Input Voltage Range
Input voltage range is single phase 88 - 264VAC (47 - 63Hz) or
125 - 373VDC for LS25 to 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).
Note : LS series able to withstand Input Surge of 300VAC for 5 seconds.
LS150 – Selectable voltage range
Selected Range
Applicable Input
Voltage Range in VAC
Applicable Input
Voltage Range in VDC
115 88 - 132 NA
230 176 - 264 248 - 373
󱫂 Output Voltage Range
V.ADJ trimmer is for output voltage adjustment within the range
of specifications. Turning the trimmer clockwise will increase
the output voltage. Note over voltage protection ( OVP) func-
tion may trigger if the output voltage is increased excessively.
󱫄Inrush Current
Power Thermistor is built in to protect the circuit from Inrush
Current. Please select suitable input switch and fuse rating
in case of re-input the power at high temperature.
󱫆Over Voltage Protection (OVP)
The OVP function will shutdown the output except for LS25.
The input need to be removed for a few minutes, and then re-
input for recovery of the output. OVP setting is fixed and can-
not be adjusted externally.
Note : For LS25, OVP function will cause the output into ”hic-
cup” mode and damage the unit.
󱫈Over Current Protection (OCP)
OCP function operates when the output current exceeds OCP
specifications. The output will automatically recover when the
overload condition is removed. Do not operate overload or
dead short conditions for more than 30 seconds, which could
result in damage or insulation failure.
󱫊Output Ripple & Noise
Ripple & noise are measured at 20MHz by using a 300mm
twisted pair of load wires terminated with a 0.1uF film capaci-
tor & 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.
At low temperature, large ripple & noise may also be observed
due to large ESR of the internal Electrolytic Capacitors espe-
cially at -25degC. Output voltage rise may not be smooth dur-
ing initial turn on at low temperature.
3. Explanation of Functions and Precautions
•Input must be off when making connection.
•Connect FG terminal to ground terminal of the equipment.
•The output load line and input line shall be separated and twisted to improve noise immunity.

LS Series
󱫀Isolation Test
Isolation resistance between output and FG (chassis) shall be
more than 100MΩat 500VDC. For safety, voltage setting of DC
isolation tester must be done before the test. Ensure that the
unit is fully discharged after the test.
(A) Output - FG (chassis) : 500VDC, 100MΩor more
󱫂Withstand Voltage
This series is designed to withstand 3.0kVAC between input
and output, 1.5kVAC between input and FG (chassis) and
500VAC between output and FG (chassis) each for 1 minute.
When testing withstand voltage, set current limit of with-
stand voltage test equipment at 20mA (Output-FG (chassis) :
100mA). The applied voltage must be gradually increased from
zero to testing value and then gradually decreased for shut
down. When timer is used, the power supply may be damaged
by high impulse voltage at timer switch on and off. Connect
input and output as follows.

󱫌Series Operation
For series operation, either method ( A ) or ( B ) is possible.
Method (A)
Method (B)
󱫎Parallel Operation
(A) Operation to increase the Output Current is not possible.
(B) Operation as a Backup Power Supply is possible as follows.
1. Set the power supply output voltage higher by the
amount of forward voltage drop (VF) of the diode.
. Please adjust the output voltage of each power supply
to be the same.
. Please use within the specications for output voltage
and output current.
