DL‐120‐24‐00‐00‐00  Direct‐to‐Liquid Thermoelectric Assembly      Thermoelectric cooling unit for medical and industrial applications The Direct-to-Liquid Series thermoelectric assembly (TEA) offers dependable, compact performance by cooling objects via liquid to transfer heat. Heat is absorbed through a cold block and dissipated thru a second liquid heat exchanger. The thermoelectric modules are custom designed to achieve a high coefficient of performance (COP) to minimize power consumption. This   product series is available in a wide range of cooling capacities and voltages. Custom configurations are available, however, MOQ applies. The liquid heat exchanger is designed to accommodate distilled water with glycol. Corrosion resistant turbulators are enclosed inside channels to increase heat transfer. Mating port adaptors are sold separately.   FEATURES APPLICATIONS  Compact form factor  Medical Diagnostics  Reliable solid-state operation  Industrial Lasers  Precise temperature control  Medical Lasers  Bi-metal thermostat for overheat  Analytical Instrumentation  protection  RoHS compliant      Americas: +1.919.597.7300   Europe: +46.31.420530      Asia: +86.755.2714.1166  ets.sales@lairdtech.com  www.lairdtech.com DL‐120‐24‐00‐00‐00  Direct‐to‐Liquid Thermoelectric Assembly                 SPECIFICATIONS  TECHNICAL    Technology  Thermoelectric modules, liquid cooling, closed  loop (non‐mixing), filterless, non‐refrigerant  Cooling at ΔT = 0°C  135W (461 Btu/h)   1 Voltage (nominal / maximum)   24/28 VDC   COP (Coefficient of Performance)  73%  Grounding (all voltages)  Positive or negative   Current draw, ±10% (nominal / startup)  4.1/4.7 A  Weight  0.7 kg (1.5 lbs)  Connector type (on unit / mating side)   TEM: Leads, 18 AWG, Red/Black  OHT: Leads    ENVIRONMENTAL  Temperature range  ‐40°C to +62°C (‐40°F to +143°F)   Hi‐Pot Test  750 VDC   Over temp Thermostat  75°C±5°C (167°F±41°F) on hot side heat sink    1) Max ripple 5% DL‐120‐24‐00‐00‐00  Direct‐to‐Liquid Thermoelectric Assembly         MECHANICAL DRAWING      For overheating protection, the cooler is equipped with a bimetal thermostat. The maximum rating for the thermostat is 8 A dc. For systems with 8 A or less, the thermostat can be connected directly in series with the thermoelectric modules (TEMs). Otherwise, connect the TEMs to the power source through a relay of suitable rating which state is controlled with the bimetal thermostat. Note: Cold block requires insulation to minimize moisture build-up under dew point conditions.                            THR‐DS‐DL‐120‐24‐00‐00‐00_083115   Any information furnished by Laird and its agents is believed to be accurate and reliable. All specifications are subject to change without notice. Responsibility for the use  and application of Laird materials rests with the end user, since Laird and its agents cannot be aware of all potential uses.  Laird makes no warranties as to the fitness,  merchantability or suitability of any Laird materials or products for any specific or general uses.  Laird, Laird Technologies, Inc or any of its affiliates or agents shall not be  liable for incidental or consequential damages of any kind.  All Laird products are sold pursuant to the Laird Technologies’ Terms and Conditions of sale in effect from time  to time, a copy of which will be furnished upon request.  © Copyright 2014 Laird Technologies, Inc.  All Rights Reserved.  Laird, Laird Technologies, the Laird Logo, and other    marks are trademarks or registered trademarks of Laird Technologies, Inc. or an affiliate company thereof.  Other product or service names may be the property of third  parties.  Nothing herein provides a license under any Laird or any third party intellectual property rights.
