AVR R250 AVR R-250 AVR R 250 - GOOD QUALITY

Automatic Voltage Regulator (AVR) compatible with Leroy Somer R250

Features :
Compact size, robust and high reliability
Innovative heat sink significantly increases cooling efficiency
Load Acceptance Module (LAM) protection
Soft start voltage ramping
Over excitation protection
Digital low frequency protection circuit, prevents thermal drift
EMI suppression
Built-in high capacity fuse

Hybrid analog-digital AVR for self-excited (shunt) generators, with two-line sensing. Compatible with Leroy Somer R250 and can also replace R230, with additional heat removal capabilities for higher reliability.

Voltage regulation at +/- 0.5% of constant speed and steady rate
Regulation value does not depend on the load applied
It is applicable in harsh environments with elevated levels of vibration
Offers a fast response time of 500 ms for transitory voltage variation of +/- 20%
Phase to neutral voltage sensing
Management of impact loads using the latest microprocessor technology
Supply voltage/range detection of 85 through 139 v
F1 slow fuse of 250 v 8 A (capable of supporting 10 A for 10 seconds and a breaking capacity of 30 kA)
Potentiometer P1 for Voltage setting
Potentiometer P2 for Stability setting
The option of adding an external potentiometer for remotely adjusting voltage
The 50 Hz/60 Hz frequency selector for LAM (Load Acceptance Module) adjustment and U/F function
