The output voltage of the device B5-9 is adjustable from zero to the maximum 100V ten steps with smooth overlap between them. In the range from 0 to the output voltage 2V parameters are not specified.
The basic error of the output voltage of the power supply B5-9 does not exceed:
± 3% for the maximum value;
- In digitized points 10 to 90B through 10B is defined by the formula
Δ = ± (0,03 V to +0.2 V)
where V to - nominal value of the digitized points of the scale unit.
Output jacks of the unit B5-9, isolated from the hull. Allowed ground plus or minus output voltage.
Output voltage ripple on the nests B5-9 in the control range from 2V to a maximum value shall not exceed the effective value of 1 mV at an acceptable load current.
Instability of output voltage regulation range from 2 to 100 V, when the supply voltage at 10% (for frequency 50 Hz) and ± 5% (for the frequency of 400Hz) from a nominal exposure for the extreme values for 1 or 5 minutes at any admissible load current must not exceed ± 0,03% respectively and ± 0,1%. The instability of the maximum output voltage of 100 V when the tone of the load from zero to the maximum permissible load current 1A does not exceed 0.1%.
The temperature coefficient of the output voltage in the range of 2 to 100 V when the ambient temperature of 5 ° C to 40 ° C at the maximum allowable load current does not exceed 0,025% / ° C after warm-up time. Output voltage drift over 8 hours of continuous operation of the power supply B5-9 does not exceed 0.2%.
Protect the device against short circuit and overload relay when the load current is exceeded by 10-60% of the maximum permissible value 1A.
