| POWER |
|
| Current |
|
16, 25, 40, 63, 80, 100, 125 and 160 amps three phase at 45 Deg. C |
| Voltage |
|
200 to 500VAC |
| Frequency |
|
47 to 63 Hz |
| AUXILIARY SUPPLY |
No Auxiliary supply is required as the 7300S derives its own internal,
synchronized supply |
| FAN SUPPLY |
None required up to 100 amps (natural convection). Above 100amps; 115V or 230V (10VA) |
| LOAD |
|
Three Phase industrial load: |
| Use category |
AC-51 Resistive load with low temperature coefficient |
| |
AC-55b Short wave infrared elements (for units ≤100A) |
| Load configuration |
|
Star with neutral (4S) |
| |
Star without neutral (3S) |
| |
|
Closed delta (3D) |
| |
|
Open delta (6D) |
| FUSES |
|
High speed fuses are external for thyristor ratings up to and including 100 amps, internal above 100amps
The fuses can be called up as part of the ordering code (High speed fuses not recommended for SWIR loads) |
| INPUT |
DC Logic (LDC) |
4.5 to 32 VDC (ON > 4.5V, OFF < 2V) or (ON > 9mA, OFF < 0.5mA) 32VDC maximum. |
| |
AC Logic (HAC) |
100 to 230VAC (ON > 85VAC, OFF < 10VAC) 253VAC maximum. Impedance 7K at 50 Hz |
| DC analogue (ATP) |
4-20mA (10VDC max.) |
| FIRING MODE |
|
For Logic inputs the firing is ON/OFF with zero voltage switching. |
| |
|
For analogue 4-20mA input the firing mode is Fast Cycle firing. The cycle time at 50% demand is 0.6 seconds (0.3 seconds ON and
0.3 seconds OFF). Output linearity better than + or - 2%. Open loop control (no supply voltage compensation) |
| INDICATION |
|
Green LED for supply ‘ON’. Green LED for Heat ‘ON’. Plus a range of diagnostic indicators |
| ALARMS (OPTION) |
|
| Diagnostic alarms (DLF) |
Serious Alarms: Unit overtemperature, thyristor short circuit and load open circuit signalled by set LED and relay contact
Partial load failure: Detects the failure of at least 1 element out of 4 in 3S, 4S, 6D configuration and 1 element out of 3 in 3D
configuration signalled by DLF LED and relay contact |
