Manual Control "LDcontrol" for HV Test Systems with resonant test set (variable frequency)

The application of "LDcontrol" is the manual control of HV power supplies with variable frequency technology.

• The control is qualified for the design of HV test fields which emergency stop and safety circuits meet the requirements of Performance Level d/e according to standard EN ISO 13849-1 and up to category 4 according to standard EN 954-1 respectively.
• The switch-on/off procedure is in accordance with DIN EN 50191.
• The control has been developed on the basis of DIN EN 61010-1 and DIN EN 61326-1.

• Ease of use
• Meet the latest safety requirements and standards
• Remote interface terminal allows a later upgrade to an automated test system

Common parameters:

• Control of Main Switch and Operating Contactors
• Overvoltage protection on secondary side and overcurrent protection on primary side with fast HV switch-off
• Push-buttons for HV ON/OFF
• Push-button Emergency Stop, additional Emergency Stop push-buttons may be connected
• Push-buttons HV UP/DOWN
• Connecting plug for the external safety circuit
• Digital display for high voltage
  - Accuracy: 1 % from 10 to 100 % of nominal voltage (in
  accordance with DIN EN IEC 60060-1)
  - Displayed value: Peak/square root (standard), factory-
  provided pre-adjustment to peak value (optional
• Digital display for primary and secondary current
  - Accuracy: 5 % from 10 to 100 % of nominal current
  - Displayed value: True RMS
• Digital display of frequency (in kHz)
• Frequency adjustable between 40 - 400 Hz
• Limit for secondary current and voltage adjustable via potentiometer
• LEDs for signaling current state of the control
• Monitoring of the lower limit switch of the regulating transformer - contactor "HV on" can only be switched on in MIN-position of regulating transformer
• Additional connector pins for external warning lamp (red/green)
• Remote interface terminal allows a later upgrade to an automated test system
• Mains: 115 V or 230 V, 50/60 Hz
• Overall dimensions: 19"-plug-in module, 4 HE

• Dissipation and Capacitance Measuring System TD SMART
• Partial Discharge Measuring Devices PD SMART or LDS-6
