JUMO 709040 TYA-110 thyristor power unit Operating Manual - Manual (Page 10)

1 Introduction
10 Power units 02.06
1. Rated load voltage = supply voltage for the control electronics
1.4.1 Type extensions (extra codes)
TR Extended version, with indication of part-load failure (adjustable by trimmer) or
blown fuse through common relay contact and LED.
This version also includes:
- Current limiting (internal, external) and rated current adjustment at I
≤ I
N
/2
- Free selection of the subsidiary control-loop type (V
2
, I
2
or P).
A free-running economy circuit can be implemented with P-control!
- Power level output signal can be switched to: V
2
, P, I

TO as for TR, but with signaling via optocoupler
MS Master-slave circuit: 2 pre-assembled power units on a mounting plate, ready
for connection.
1.4.2 Standard accessories
1 Mounting plate for wall-mounting
