PSC/PSL Series Positive Switching Regulators The PSC and PSL Series positive switching regulators are designed as power supplies for electronic systems, where no input-to-output isolation is required. Their major advantages include a high level of efficiency, high reliability, low output ripple, and excellent dynamic response. Models with input voltages up to 144 V are specially designed for secondary switched and battery- driven mobile applications. The converters are suitable for railway applications according to EN 50155 and EN 50121. Two type of housings are available allowing operation up to 71 C. The PSC Series is designed for wall or chassis mounting with faston connections, whereas the PSL Series is designed for insertion into a 19 DIN-rack and exhibits a H11 connector. 32 Various options are available to adapt the converters to different 1.3 applications. 88 151 3.5 5.9 Features RoHS lead-free-solder and lead-solder-exempted products are available 5 year warranty for RoHS compliant products with an extended temperature range Input voltage up to 144 VDC Single output of 3.3 to 48 VDC No input-to-output isolation High efficiency up to 97% Extremely wide input voltage range Low input-to-output differential voltage Very good dynamic properties Input undervoltage lockout Output voltage adjustment and inhibit function 107 4.2 Continuously no-load and short-circuit proof 3 U All boards are coated with a protective lacquer 168 37 6.6 1.5 Safety-approved to the latest edition of IEC/EN 60950-1 8 TE and UL/CSA 60950-1 Table of Contents Electromagnetic Compatibility (EMC) .................................13 Description............................................................................1 Model Selection ....................................................................2 Immunity to Environmental Conditions ...............................15 Functional Description ..........................................................5 Mechanical Data .................................................................16 Electrical Input Data .............................................................6 Safety and Installation Instructions .....................................17 Electrical Output Data...........................................................8 Description of Options ........................................................19 Accessories ........................................................................21 Auxiliary Functions .............................................................12 belfuse.com/power-solutions BCD20027-G Rev AD, 01-Oct-2018PSC/PSL Series Positive Switching Regulators Model Selection Table 1: PSC Series 2 Output Output Operating input Nom. input voltage Efficiency Type Options voltage current voltage range designation V V I A V V V V % % o nom o nom i o nom min typ 5.1 10 8 - 80 40 77.5 79 PSC5A10-9iRG -7, L, C, D, non-G 5.1 11 8 - 40 20 78 79 PSC5A11-2 --- 5.1 12 7 - 40 20 83.5 85.5 PSC5A12-9iRG -7, L, P, C, D, non-G 1 12 6 18 - 144 60 88 89 PSC126-9iRG -7, L, C, D, non-G 12 8 15 - 80 40 91 93 PSC128-9iRG -7, L, P, C, D, non-G 12 9 15 - 40 30 89 90 PSC129-2iR --- 1 15 6 22 - 144 60 89 91 PSC156-9iRG L, C, D, 15 8 19 - 80 40 90 92.5 PSC158-9iRG -7, L, P, C, D, non-G 15 9 19 - 40 30 91 93.5 PSC159-2iR --- 1 24 6 31 - 144 60 93 94 PSC246-9iRG -7, L, P, C, D, non-G 24 8 29 - 80 40 93 95 PSC248-9iRG -7, L, P, C, D, non-G 24 9 29 - 60 40 94 96 PSC249-2iR --- 1 36 6 44 - 144 80 95 96 PSC366-9iRG -7, L, P, C, D, non-G 36 8 42 - 80 60 95 96.6 PSC368-9iRG -7, L, P, C, D, non-G 1 48 6 58 - 144 80 96 97 PSC486-9iRG -7, L, P, C, D, non-G 1 Surges up to 156 V for 2 s see Electrical Input Data 2 Efficiency at V and I . i nom o nom 3 Obsolete.
