交換 & 選定ガイドライン

1. Select the same 6038 サイズ, 24 VDC fan with tachometer speed feedback (FG signal) (例えば, FFB0624EHE). If no fault alarm is required, a 2-wire standard 6038 24 VDC fan can be used, but inverters will trigger fan fault alarms.
2. 取付穴間隔: Standard 50×50 mm for 60 mm fans.
3. Airflow direction: Must match the intake/exhaust direction of the original fan.

よくあるトラブルシューティング

Fan does not spin: チェック 24 VDC電源, wiring harness and rotor jamming.

Fan runs but the drive reports a fan fault: Broken yellow tachometer wire or damaged Hall sensor inside the fan.

異音: Worn ball bearings; direct replacement is required (ball bearing fans cannot be repaired after service life decay).

Mandatory requirements for direct interchange (failure to meet will trigger inverter fault alarms):

60×60×38 mm, 24 VDC, 約. 0.4 あ, 3-ワイヤー (Red +24V / Black GND / Yellow FG tachometer), dual ball bearings, open-collector rotor lock tach signal.

1. Preferred Domestic Drop-in Replacements (工業用グレード, Direct Pin-to-Pin Swap)

1) Dongxingyue (DXM, widely used for inverters)

モデル: DF6038B24M-FG (3-wire with RD tach feedback)

Spec: 24 VDC, 0.4~0.55 A, dual ball bearing, 7000~9000 RPM, FG tach output

Fully compatible with FFB0624SHE-R00; no wiring modification needed.

2) KAKU (KAKU, highest stability for industrial fans)

モデル: KA6038B24H-FG

Spec: 24 VDC, 0.42 あ, 6038 サイズ, 3-wire speed detection, IP55 rating

に最適 24/7 連続運転; first choice for inverters and servo drives.

3) SNOWFAN (Cost-effective option)

モデル: YY6038L24B-FG (3-wire tach version)

Spec: 24 VDC, 0.38~0.42 A, dual ball bearing with FG signal

重要: Only purchase the 3-wire FG tach model; avoid 2-wire non-feedback versions.

4) Yimeng (YM, commonly used for industrial power supplies)

モデル: YM2406PTB3 (6038, 3-wire with feedback)

0.4 電流, 7000 回転数; pinout fully consistent with Delta fans.

1. General Alternative Models (Must specify: 3-ワイヤー + FG tach feedback when ordering)
2. Shengshida: 6038-24V-0.4A-FG
3. Weiyixin: 回転数 | 2-ワイヤー / 3-ワイヤー | 低速 / 低騒音

Ⅲ. Factory Upgrade Replacement (PFB0624 Series, In-Stock Direct Swap)

The FFB series is end-of-life; the corresponding Delta upgraded models are listed below:

1. FFB0624SHE-R00 → PFB0624SHE-R00 (3-wire with tach; ピン配列 100% 互換性がある)
2. FFB0624EHE-R00 → PFB0624EHE-R00
3. Critical Purchase Notes
4. Inverter applications must select the -R00 (3-wire FG tach feedback) バージョン; 2-wire -F00 versions will cause fan fault alarms.
5. Fixed pin assignment: Red = +24 VDC, Black = GND, Yellow = FG tach signal.
6. If only FFB stock is available, prioritize FFB0624SHE-R00; if out of stock, switch directly to PFB0624SHE-R00.

Delta PFB0624 Series (6038 24 VDC) – Applications

コア機能: Dual ball bearings, 工業グレード, high static pressure, optional -R00 3-wire FG tach feedback. It is the direct upgraded replacement for the obsolete FFB0624 series, designed for forced air cooling inside sealed equipment. Models with tach feedback (-R00) are required for systems with fan fault monitoring.
