[Woodward] Woodward PGPL electro-hydraulic actuator/driver(37519 G version)

2025-09-06

Technology type: Electro hydraulic integrated actuator, including proportional drive interface, capable of receiving electronic controllers (such as Woodward 2301A series, 700 series, etc.) Peak ® The 0-200mA position signal output by the 150 and 505 controllers is controlled by a torque motor and a follow-up pilot valve to drive the output shaft, and coupled with a contactless position sensor to achieve closed-loop control.
Alternative value: Used to replace traditional hydraulic mechanical governors such as PG-PL, PGD, PGL, etc., retaining the convenience of the original PG type transmission and connecting rod system, while possessing high precision and flexibility of electronic control.

[Woodward] Woodward ESDR 4/4T current differential protection relay

2025-09-05

ESDR 4/4T is a series of current differential protection relays launched by Woodward, specifically designed for three-phase current differential protection of generators, motors, and interconnecting transformers. By accurately monitoring the current on both sides of the protection area, identifying fault types, and triggering selective tripping, it ensures the safe and stable operation of power equipment. It is divided into two versions: ESDR 4 (for generators/motors) and ESDR 4T (for generators/motors/interconnecting transformers), and is suitable for harsh power consumption scenarios in industrial, energy, and other fields.

[Woodward] Woodward 2301A 9907 series electronic load distribution and speed controller

2025-09-03

Core function: Simultaneously achieve two major functions of speed control and load distribution - speed control maintains stable speed of the prime mover (engine/turbine), load distribution ensures proportional load sharing when multiple units are connected in parallel, avoiding single unit overload or uneven load.
