The Siemens MICROMASTER 410/420/440 variable frequency drive product sample provides specifications, circuit diagrams, ordering data and application…
The MICROMASTER 410/420/440 series are low‑voltage variable frequency drives designed for pumps, fans, conveyors and other industrial applications. They support single‑phase (100‑120 V or 200‑240 V) and three‑phase power supplies and feature self‑cooled heat sinks, built‑in B‑class EMC filters and RS‑485 communication.
The document contains detailed technical data such as power ranges, input/output frequencies, overload capacity and protection functions, as well as optional accessories like EMC filters, line reactors, and advanced operation panels. Ordering numbers, dimensions, weight and environmental specifications are also listed. This manual is written in Chinese.
| Power range (single‑phase 200‑240 V) | 0.12 kW – 0.75 kW |
|---|---|
| Input frequency range | 47 Hz – 63 Hz |
| Output frequency range | 0 Hz – 650 Hz |
| Power factor | 0.98 |
| Efficiency | 96 % – 97 % |
| Overload capacity | 150 % of rated current for 60 s, then 85 % for 240 s |
| Digital inputs | 3 programmable non‑isolated inputs (plus optional 4th via analog) |
It accepts 200 V‑240 V ±10 % single‑phase AC (0.12 kW‑0.75 kW) and 100 V‑120 V ±10 % single‑phase AC (0.12 kW‑0.55 kW).
The drive provides three fully programmable non‑isolated digital inputs, and a fourth input can be used via the analog channel.
It can handle 150 % of the rated current for 60 seconds, followed by 85 % for 240 seconds in a 5‑minute cycle.
