Non-isolated DC/DC converter

step-upstep-downencapsulated

Short description
Step-up/step-down (boost/buck) DC-DC converter accepting DC 8V–40V input and providing regulated DC 12V ±0.25V output. Available output currents: 1A–25A across three size groups. Non-isolated topology, IP67 ingress protection, typical efficiency up to 96%. Certificates: CE, FCC, RoHS.

Features

• Synchronous rectification technology
• Internal resistance capacitor filter for high-temperature tolerance
• Organic silicone packaging
• Integrated protection: overheat and overcurrent protection
• Shock-, drop-, moisture- and dust-resistant construction
• High efficiency up to 96%
• Non-isolated input-output topology
• Ingress protection rating IP67 (waterproof)

Attention

• Follow label and wiring instructions during installation; do not reverse polarity.
• Do not connect input and output in reverse; this may damage the device.
• Ensure load power does not exceed the converter's maximum rating.
