DESCRIPTION
The ELV series is an economy version of our LV series. The ELV series consists of high density, low input voltage, isolated
converters with a wide input voltage range. Low input voltage converters are uncommon in the industry and the ELV series
offers the flexibility of operation with both 12V and 24V busses. This state-of-the-art converter’s features include fast transient
response, short circuit protection, over current protection, soft start, and many other features that are required for today’s
demanding applications. This series is available in both encapsulated and open frame designs.

NOTES
1. This series is available in both encapsulated and open frame designs. For open frame design add the suffix “O” to the part
number. (Ex: ELV12S15-100O)
2. Pin to pin tolerance: ±0 .01" [± 0.3mm], pin diameter tolerance: ± 0.005" [± 0.13mm].
3. Case material: 0.040" [1.02mm] thick, aluminum alloy 3003-0, per: QQA 250/2.
4. Unit comes with either 3M x 0.5 threaded thru inserts or for 0.125 thru-hole add "TH" suffix to model part number.
(Ex: ELV12S12-100TH)
5. Optional heatsink available. Please call factory for ordering details.
6. Active high enable is standard; for active low enable add the suffix “R” to the part number (Ex: ELV12S15-100R).
