T1689 Technical Manual Rev 07 Specification
MV3000 Air Cooled DELTA DELTA Rectifier Module
Page 37
2.9.1.7 A.C. Voltage Frequency
Supply frequency : 45 Hz to 63 Hz.
2.9.1.8 D.C. Link Voltage
The Output d.c. Link Voltage is detailed in Table 2–16.
Typical d.c. output: 1.35 x supply voltage (r.m.s).
2.9.1.9 Pre-Charge
Pre-charge requirements are listed in Table 2–17. The pre-charge control signal switches in the main rectifiers
when the d.c. link has finished pre-charging. The drive controller determines when the charging period is
complete. The MVRL2100-4601/2 DELTA rectifier module is capable of pre-charging:
• Up to four MVD300 or MVD500 DELTA transistor modules;
The rectifier pre-charge acknowledge signal must be connected to the MV3000e controller at PL12, to allow
drive operation. See Table 2–11.

2.9.1.10 Thermal Protection
Thermal protection is provided on each rectifier module by a thermistor and a thermostat located on each
heatplate. Connection details are given in Table 2–11. The thermostat contact is a normally closed contact and
opens at at 90°C ±3°C (194°F ±5°F).
