Delta inverters use the standard naming convention:
VFD-[Power Code][Series Code][Voltage Code][Special Function Code].
Some new models (such as the MS300 series) adopt a more detailed extended naming format.
The following provides a comprehensive explanation from four aspects: general structure, meaning of each part, typical series examples, and special function codes.
- General Model Structure (Example: VFD007E23A)
| موضع | شفرة | معنى | Example Description |
| 1–3 | VFD | Product Identifier | Variable Frequency Drive. All Delta inverters start with this. |
| 4–6 | 7 | Rated Power Code | Represents 0.75 كيلوواط (750 دبليو). Different codes correspond to different power ratings. |
| 7 | ه | Series Code | Indicates VFD‑E series (low‑power inverter with built‑in PLC). |
| 8–9 | 23 | الجهد االكهربى & Phase Code | “2” = 200–240 V, “3” = 3‑phase input. |
| 10 | أ | Special Function Code | Standard version with built‑in EMI filter. |
- Detailed Breakdown of Each Part
2.1 Power Code vs. القوة المقدرة (كيلوواط)
| Power Code | القوة المقدرة | Power Code | القوة المقدرة | Power Code | القوة المقدرة |
| 2 | 0.2 | 15 | 1.5 | 75 | 7.5 |
| 4 | 0.4 | 22 | 2.2 | 110 | 11 |
| 7 | 0.75 | 37 | 3.7 | 150 | 15 |
| 10 | 1 | 55 | 5.5 | 220 | 22 |
ملحوظة: Some high‑power models use actual power directly, على سبيل المثال, VFD110B43A = 110 كيلوواط.
2.2 Series Code & سمات
| Series Code | Series Name | Key Features | التطبيقات النموذجية |
| م | VFD‑M | ضوضاء منخفضة, حجم صغير | Small machinery, packaging, conveyors |
| ه | VFD‑E | Built‑in PLC | Automated production lines |
| ب | VFD‑B | Sensorless vector control, high torque | المشجعين, مضخات, الضواغط, cranes |
| ف | VFD‑F | For fans & مضخات, built‑in PID | التدفئة والتهوية وتكييف الهواء, cooling towers, water supply |
| MS | MS300 | Compact high‑performance general‑purpose | Small automation, replaces VFD‑M |
| MH | MH300 | High‑performance vector, servo‑grade | Positioning, tension control, sync motors |
| CP2000 | VFD‑CP2000 | Sensorless vector, high overload | General industrial machinery |
| ED | VFD‑ED | Dedicated for elevators | Passenger & freight elevators, escalators |
2.3 الجهد االكهربى & Phase Code
| شفرة | Input Power | Output | Application Region |
| 21 | 1‑phase 200–240 V | 3‑phase 0–240 V | Home/small equipment, Asia/NA |
| 23 | 3‑phase 200–240 V | 3‑phase 0–240 V | Industrial, Asia/NA |
| 43 | 3‑phase 380–460 V | 3‑phase 0–460 V | Industrial, global |
| 53 | 3‑phase 525–600 V | 3‑phase 0–600 V | High‑voltage industrial |
2.4 Special Function Suffix Codes
| Letter | معنى | Letter | معنى | Letter | معنى |
| أ | With EMI filter, معيار | ب | With braking unit | ن | Without EMC filter |
| س | Built‑in STO | ح | Enhanced heat dissipation | ص | Higher protection |
| ‑21 | Special version | ‑00 | Standard version | ‑EA | Energy‑saving for fans/pumps |
- New Extended Format (Example: VFD1A5MS43ANSHA, MS300)
| موضع | شفرة | معنى | وصف |
| 1–3 | VFD | Inverter identifier | Standard prefix |
| 4–6 | 1A5 | Rated output current | 1.5 أ (≈ 0.75 كيلوواط) |
| 7–8 | MS | رمز السلسلة | MS300 series |
| 9–10 | 43 | Voltage code | 460 V 3‑phase input |
| 11 | أ | IP rating | IP20 |
| 12 | ن | EMC configuration | Without EMC filter |
| 13 | س | Safety function | Built‑in STO |
| 14 | س | Cooling | Standard cooling |
| 15–16 | AA | Special options | Standard configuration |

- اختيار & Identification Tips
- Power matching: Select according to motor rated power; inverter ≥ 1.1× motor power recommended.
- Voltage compatibility: Confirm input phase and voltage (21/23/43, إلخ.).
- Series function: Choose by application (F for fans/pumps, E for PLC).
- متطلبات خاصة: Select protection, إي إم سي, and safety functions as needed.
- Backward compatibility: New models (على سبيل المثال, MS300) replace older ones.
- Quick Identification Mnemonic
Start with VFD,
Numbers show power,
Letters show series,
Two digits show voltage,
Suffix shows features.
With the above explanation, you can easily identify the power, مسلسل, الجهد االكهربى, and functions of any Delta inverter model for accurate selection, purchasing, and maintenance.
