Excitation Plate of Electric Generator

Technical parameters

1. Type: PC11;
2. Convert alternating voltage produced by generator to direct voltage required by generator excitor. This plate includes two rectified current, one is bridge rectifier, the other is silicon controlled rectifier, the two rectifiers can automatic transfer;
3. When generator is launched, because the remannence voltage of the generator is too low, the bridge rectifier curcuit can built generator voltage immediately to, external battery and attachments are not needed;
4. When generator voltage arises to a certain level, the silicon controlled rectifier control curcuit will automatically replace the bridge rectifier cercuit to ensure the safety and reliability of the generator excitation curcuit;
5. When generator functions well, it will form an inner ring controlled by closed-loop with AC module to maintain a 600V AC voltage for the generator;
6. When a sudden load change of the generation set occurs, it will form a outer ring controlled by closed circuit with AC module to steadily adjust the exciting voltage, the voltage will be recovered to its set value in a short time;
7. Excitation output:0110 DC voltage signal.

Guide rail temperature transmitter

Technical parameters

1. Input: Thermocouple K-type, E-type, B-type, S-type, T-type, J-type, N-type RTD Pt100 Cu100 Cu50 (three-wire or four-wire system)
2. Output: Output 4~20ma DC signal within the range. Linear with the millivolt signal input by thermocouple; linear with the input resistance signal of the RTD. Or linear with temperature signal. As an isolation temperature transmitter, input and output phases are isolated with isolation voltage of 0.5KV, increasing resistance to common-mode interference, more suitable for use with computer networking.
3. Basic error: *±0.5% F・S
4. Transmission method: two-wire system
5. Display mode: (digital) LCD four-bit display, show a sign of e ... when open circuit of thermocouple occurs with output greater than 20mA
6. Working power: Min. voltage of transmitter working power is 12V, Max. voltage 35V, rated operating voltage 24V.
7. Load: Limit load resistance is calculated as follows:
RL (max)=50 (Vmin-12) (i.e. at 24V,
load resistance can be selected within 0~600Ω)
Rated load 250Ω.
8. Normal operating environment:
a) Ambient temperature: -25°C~80°C (Regular type)
-20°C~70°C (Digital display type)
b) Relative humidity: 5%~95%
c) Mechanical vibration: f≤50hz, amplitude <0.15mm
d) In ambient air, there is no corrosive medium for chromium, nickel coating, non-ferrous metals
and other alloys.
9. Impact of ambient temperature: ≤0.05/1°C
Note: "*" Contracted products with a tolerance error of ±0.2% can be provided if specially requested by customers.
10. Mount: regular type, dedicated type, wall mounted type and guide rail type
