Heatsink is available for all models. To indicate heatsink option add “H” to the end of model number. Ex DCPSR2-5S1P2H -Due to high output power of DCPSR2-24SXX heatsink is able to be operated at least 50ºC ambient temperature without derating when applied input voltage does not exceed 30V. Other models can meet this condition without heatsink. Heatsink can be installed for higher operating ambient temperature as well. For more information, please contact factory. 2. For DCPSR2-12SXX and DCPSR3-24SXX the input should install an external 22µF/50V E/C only if the input will be switched electromechanically. CAUTION: This power module is not internally fused. An input fuse must always be used. *Due to advances in technology, specifications subject to change without notice. 7/10/2017 Wall Industries, Inc. • 37 Industrial Drive, Exeter, NH 03833 • Tel: 603-778-2300 • Toll Free: 888-597-9255 • Fax 603-778-9797 website: www.wallindustries.com • e-mail: [email protected] Page 2 of 5 Rev A DCPSR2 SERIES 30 Watts Non-Isolation DC/DC Converter Single Output DERATING CURVES DCPSR2-12S05 Derating Curve DCPSR2-12S05H Derating Curve DCPSR2-24S15 Derating Curve DCPSR2-24S15H Derating Curve EFFICIENCY GRAPHS 7/10/2017 DCPSR2-12S05 Efficiency vs. Output Load DCPSR2-12S05 Efficiency vs. Output Load DCPSR2-24S15 Efficiency vs. Output Load DCPSR2-24S15 Efficiency vs. Input Voltage Wall Industries, Inc. • 37 Industrial Drive, Exeter, NH 03833 • Tel: 603-778-2300 • Toll Free: 888-597-9255 • Fax 603-778-9797 website: www.wallindustries.com • e-mail: [email protected] Page 3 of 5 DCPSR2 SERIES 30 Watts Non-Isolation DC/DC Converter Single Output Rev A MECHANICAL DRAWINGS Standard Models PIN CONNECTION PIN DEFINE 1 +Vin 2 GND 3 +Vout Heatsink Option (“H” Suffix) S PIN CONNECTION PIN DEFINE 1 +Vin 2 GND 3 +Vout 4 Case 5 Case Notes: All dimensions in inch (mm) Tolerance: x.xx±0.02 (x.x±0.5) x.xxx±0.01 (x.xx±0.25) Pin pitch tolerance ±0.01 (0.25) Pin dimension tolerance ±0.004 (0.1) FDC 7/10/2017 Wall Industries, Inc. • 37 Industrial Drive, Exeter, NH 03833 • Tel: 603-778-2300 • Toll Free: 888-597-9255 • Fax 603-778-9797 website: www.wallindustries.com • e-mail: [email protected] Page 4 of 5 DCPSR2 SERIES 30 Watts Non-Isolation DC/DC Converter Single Output Rev A MODEL NUMBER SETUP DCPSR2 - Series Name 5 S 1P5 H Input Voltage Output Quantity Ouptut Voltage Remote On/Off & Pin Length 5: 3.0~5.5VDC S: Single 1P2: 1.2VDC Blank: No Heatsink 3.8~5.5VDC 1P5: 1.5VDC H: Heatsink 12: 4.6~36VDC 1P8: 1.8VDC 4.75~36VDC 2P5: 2.5VDC 6.5~36VDC 3P3: 3.3VDC 9.0~36VDC 05: 5VDC 24: 12~36VDC 6P5: 6.5VDC 15~36VDC 09: 9VDC 18~36VDC 12: 12VDC 15: 15VDC COMPANY INFORMATION Wall Industries, Inc. has created custom and modified units for over 50 years.
