Protection level: The standard model has an IP20 protection level (protective casing), suitable for clean environments.

Product model and specification system

1. Model coding rules

Taking "GA50U4004ABA" as an example, the meanings of each paragraph are as follows:

Product series: GA500; Region codes: U (Americas), M (Moisture resistant), S (Vibration resistant);

Voltage level: B (240V single-phase), 2 (240V three-phase), 4 (480V three-phase);

Type of chassis: B (IP20/protective type), J (no heat sink type); EMC filters: A (no built-in), E (built-in).

2. Classification of core specifications

Voltage type, power range, output current (regular/heavy load)

240V single-phase input 1/6~5HP (0.1~3.7kW) conventional: 1.2~12.2A; heavy load: 0.8~17.5A

240V three-phase input 1/6~30HP (0.1~22kW) conventional: 1.2~82A; heavy load: 0.8~75A

480V three-phase input 1/2~40HP (0.2~30kW) conventional: 1.2~60A; heavy load: 1.2~45A

3. Special model variants

Covering variants such as high-frequency output (2000Hz), anti vibration type, moisture resistant type, and no heat sink type, some variants (except for high-frequency output) have a delivery cycle of 16 weeks when there is no forecast order.

Core selection plan

1. Explanation of single-phase input derating

When a three-phase driver is used in a single-phase input scenario, it needs to be reduced in capacity. For example, the 240V three-phase 2001 model driver reduces the conventional power from 1/6HP to 1/8HP during single-phase input, which can be avoided by a single-phase converter. The power factor is close to 1, and the total harmonic distortion rate is less than 10%.

2. Installation method selection

The IP20 standard model supports three installation methods:

Installation inside an independent cabinet (with built-in heat sinks, no additional brackets required);

Installation inside an independent cabinet (with external heat sinks, requiring an external heat sink adapter);

Direct installation of inorganic cabinet (requires UL Type 1 adapter).

3、 Core selection plan (including capacity reduction and installation)

1. Single phase input derating rules

When a three-phase driver is used for single-phase input scenarios, it needs to be reduced in capacity. Taking the 240V three-phase model as an example, the core reduction data is as follows (partial excerpt):

Driver model (GA50U) without reactor (Open) without reactor (UL Type 1 closed) with reactor (AC input type)

Motor Power (HP) Current (A) Motor Power (HP) Current (A) Reactor Model Corresponding Power (HP)

2001 - - 1/8 0.61 URX000283 1/8

2002 1/8 0.61 1/4 1.16 URX000291 1/4

2004 1/4 1.16 1/3 1.52 URX000295 1/3

2006 1/3 1.52 1/2 2.20 URX000299 1/2

Solution: Capacity reduction can be avoided through a "single-phase converter (SPC)", such as the 240V 20HP single-phase converter (SPBC-240-20HP), which supports a maximum motor load of 20HP and an input current of 79A. It needs to be paired with a DC link reactor (URX000530).

2. Installation method and adaptation requirements

The IP20 standard model supports three installation methods, which need to be selected according to the environment:

(1) Classification of installation methods

Installation method, applicable scenarios, key requirements, and compatible accessories

Method 1: Inside an independent cabinet (with built-in heat sinks) in a clean room with sufficient space and no need for additional brackets. The cabinet should be well ventilated-

Method 2: Inside an independent cabinet (with external heat sinks) in a clean room, if the cabinet space is limited, an external heat sink adapter should be selected according to the drive model. For example, the 240V single-phase B001 model is compatible with the ZPSA-GA50V1-1 external heat sink adapter (ZPSA series)

Method 3: Install the inorganic cabinet directly in the clean room, and all models without dedicated cabinets need to be equipped with UL Type 1 adapters. For example, the 240V single-phase B001 model is compatible with the ZBAA-GA50V1-1 UL Type 1 adapter (ZBAA series)

🔶 4-42 🔶 4-43 🔶 4-44 

(2) DIN rail installation adaptation

Only models with a width<170mm and a height<128mm are supported, such as 240V single-phase B002ABA compatible with ZPZ-GA50V1, B010ABA compatible with ZPZ-GA50V2, and high-power models (such as B018ABA) that require a dedicated kit (EZZ08122D) 🔶 4-237.
