- RoHS compliant, 5-year warranty
Through-Hole
Cosel's through-hole DC/DC converters are isolated modules in DIP and SIP packages, covering power levels from 1.5 W to 30 W. Wide input voltage ranges and a choice of single, dual or triple outputs make them suited to industrial, telecom and embedded applications where solderability and reworkability matter.
Key features:
- DIP and SIP packages
- Wide input range: 4.5 – 76 VDC (series dependent)
- Output power: 1.5 – 30 W
- Single, dual and triple output options
- Built-in overcurrent and overvoltage protection
- Remote ON/OFF (select models)
- Optional conformal coating for harsh environments
- Operating temperature: –40 °C to +85 °C
DIN Rail
Cosel's DIN rail DC/DC converters are designed for direct installation onto standard 35 mm DIN rails in control panels and distribution boards. They deliver stable, regulated output power for distributed industrial systems across a wide range of input and output voltage configurations.
Key features:
- Standard 35 mm DIN rail mounting
- Wide input voltage range
- Regulated single output
- Built-in protection: OCP, OVP, thermal
- Suitable for industrial control cabinets and automation systems
19" Plug-In
Cosel's 19" plug-in DC/DC converters are designed for installation into standard 19" rack systems, delivering reliable, high-density power in telecom, server and industrial rack-mounted environments.
Isolated
Cosel's isolated DC/DC converters provide galvanic isolation between input and output, protecting sensitive downstream circuits and meeting the safety requirements of medical, industrial and railway applications. Isolation voltages reach 1,500 VDC on compact PCB-mount series.
Key features:
- I/O isolation: 1,500 VDC (PCB-mount series)
- Available across all package types: SMD, DIP, SIP, brick
- Single, dual and triple outputs
- OCP, OVP and thermal protection
- Compliant with IEC 62368-1, IEC 60601-1 (medical) and EN 50155 (railway) depending on series
Non-Isolated (POL)
Cosel's non-isolated point-of-load converters step down voltage directly at the load with high efficiency, a minimal footprint and fast transient response. They are ideal for powering FPGAs, processors and other digital loads from a distributed power bus.
Key features:
- Non-isolated synchronous step-down topology
- Very high efficiency
- SMD and through-hole mounting
- Adjustable output voltage
- Designed for embedded computing, server boards and storage systems
