1. What input voltage does the KH90F support?

The KH90F accepts a universal single-phase input range of 85–264Vac at 45–66Hz. It can also operate from an 88–250Vdc input, supporting both AC and high-voltage DC distribution systems.

2. What output models are available?

The KH90F is available with two output options. The 12Vdc model supplies up to 6.8A and 81.6W, while the 24Vdc model provides up to 3.8A and 91.2W.

3. Does the KH90F include active power factor correction?

Yes. The KH90F incorporates active PFC and complies with IEC 61000-3-2 Class A. Its typical power factor is 0.98 at 115Vac and 0.86 at 230Vac under full-load conditions.

4. Does the KH90F require a cooling fan?

No. The KH90F uses natural convection cooling and does not require an integrated fan. It operates from -20°C to +70°C, subject to the derating and mounting requirements specified in the datasheet.

5. What applications and approvals does the KH90F support?

The KH90F is suitable for industrial automation, factory equipment, instrumentation, machine building and process-control systems. Approvals include UL, C-UL, EN, UL508 and ATEX, with selected options supporting NEC Class 2 requirements.

KH90F Cosel

The KH90F Cosel 90W DIN rail power supply provides regulated DC power for factory automation, instrumentation, machinery and process-control systems. The 12Vdc model supplies up to 6.8A and 81.6W, while the 24Vdc model delivers up to 3.8A and 91.2W. Adjustable output voltage allows the supply to be matched to different load and distribution requirements. The compact 50mm-wide enclosure uses natural convection cooling and operates from -20°C to +70°C, subject to derating. Built-in overcurrent and overvoltage protection, active PFC and industrial approvals support integration into demanding control cabinets.
