Product Introduction
The TDK-Lambda HWS600-24 is a high-power enclosed AC/DC supply intended for industrial and equipment-level power conversion. It accepts 85–265VAC or 120–330VDC input and provides a regulated 24VDC output, making it suitable for control panels where PLCs, I/O equipment, relays, instrumentation, and other DC loads share a common power source.
The 27A output capability gives the HWS600-24 substantially more capacity than typical DIN-rail control supplies. Its chassis-mounted construction and forced-air cooling should, however, be considered during panel design; this is not a small DIN-rail replacement that can simply be dropped into an existing control cabinet.
HWS600-24
Engineering Pain Point
With the HWS600-24, the main engineering issue is usually thermal management rather than nominal output voltage. At 648W, the supply uses forced-air cooling, so cabinet airflow, fan condition, ambient temperature, clearance, and load profile all matter. A replacement with the same 24V rating but substantially lower current capacity may operate normally during commissioning and then become a nuisance failure as the panel approaches its normal operating load.
Typical Applications
- PLC and DCS control cabinets requiring a high-current 24VDC bus.
- Industrial automation panels supplying multiple I/O modules, relays, sensors, and control devices.
- Machine-control equipment requiring a single-phase universal AC input.
- Control systems where DC input capability provides an alternative power-feed arrangement.
- Industrial equipment requiring adjustable 24V output within the documented 19.2–28.8V range.
Technical Pitfalls to Avoid
- Do not size the replacement from voltage alone.
HWS600-24 provides up to 27A / 648W. Confirm the actual continuous load and startup/inrush requirements of the connected equipment. - Account for forced-air cooling.
TDK-Lambda specifies forced-air cooling for this model. Fan failure or restricted airflow can materially affect thermal performance. - Do not confuse with /HD.
The/HDversion is a harsh-environment variant with additional vibration/shock specifications and a slightly different operating-temperature specification. The suffix is part of the ordering identity. - Check the output setting before connecting sensitive electronics.
The documented adjustment range is 19.2–28.8VDC. Do not assume a replacement unit is still at exactly 24.0V after previous adjustment or service work. - Check cabinet dimensions and airflow clearance.
The unit is approximately 165 mm deep × 100 mm wide × 82 mm high and weighs about 1.6 kg. Mechanical fit and ventilation need to be verified before replacement.
Related Products
- TDK-Lambda HWS300-24 — same HWS family and 24V output class, but approximately half the power capacity at 336W; suitable only where the DC load is lower.
- TDda /HD — 24V, 27A, 648W version designed for harsher environmental requirements; verify the environmental specification before substitution.
- TDda /ME — 24V, 27A medical-equipment variant with medical safety certifications; it is not simply an interchangeable suffix.
- TDda /PV — 24V variant with an output-voltage external-control option; verify whether the installed system requires this function.
- TDK-Lambda HWS1000-24 — higher-capacity HWS unit for applications exceeding the output requirement.
- TDK-Lambda HWS1500-24 — substantially higher-power HWS configuration for larger 24VDC loads.
Procurement check:an replacement, match the complete designation rather than selecting by “24V/600W” alone. Verify input range, output adjustment, 27A current requirement, mounting dimensions, cooling arrangement, and any suffix such as /HD, /ME, or /PV against the installed unit.
