General

HYCA type AC DC leakage current sensor

Introduce:

HEYI Electrical company ASCT brand new product  HYCA type AC DC leakage current sensor is a Leakage Protection Residual Current sensor specifically developedfor EV-charging providing all-current sensitivity. Charging of electric vehicles ata standard wall socket or a wall box requires protection devices against DC faultcurrents to avoid electric shock. Installed type A residual current circuit-breakers(RCCBs) are unable to identify and deactivate DC fault currents.

Features:

  • Small volume and footprint for integration into compact IC-CPD.
  • Avoids hazardous situations with DC fault currents.
  • Protects RCCB type A from saturation.
  • Saves costly type B RCCD.
    Volume optimized.
  • AC/DC-current sensitivity at low cost.
  • Protects RCCB type A from saturation.
  • Self-monitoring and test functions.
  • Robust mechanical design suitable for IC-CP.

Technology:

  • ault current detection according to IEC 62752 or UL 2231.
  • Frequency range DC up to 2 KHz.
  • Load current up to 80 Arms (1-phase) or 3 x 32 Arms (3-phase).
  • Switching output for 6 mA DC and 30 mA AC (acc. to IEC 62752)
  • Integrated self-monitoring and test functions.
  • Measurement resolution of 0.2 mA.
  • Variants with pass through opening or with integrated primary conductors.
  • Differential current range 0~300 mA.
  • Robust mechanical design suitable for IC-CPD environmental requirements (e.q. drop test)
  • Widely usable in harsh electronic environment (e.g, resistant to external maanetic fields)
  • The sensor can trigger an automatic shut-off in case ofhazardous electrical faults (DC and AC) according to lEC 62752 or UL2231.

Tecnial data

Pin number Symbol Pin typ Functions
 1 Error  / Open-collector output pin for indicating the system
fault condition.
When no system fault, this pin will be conducted
to GND.
When system fault occured, this pin will be highimpedance.
2 TEST-IN OUTPUT When this pin been conducted to 0VDC, module will calculate the zero-point-drift and store the value to register in the MCU to finish the callbration operation.
After calibration finished, system will internally generate simulated residual current, to check whether module can do the correct response.During this procedure, X30-OUT & X6-OUT will turn to highimpedance if module working correct.
Attention:
When using the TEST-IN function, the main circuit must be cut-off to ensure no r esidual current flow When using this pin function, please follow the time diagram figure.
3 X6-OUT OUTPUT If residual current exceeds pre-set DC trippling value(for this module typically 4.6 mADC),this output is in a high-impedance state When the total residual current r.m.s exceeds pre-set all-current trippling value, this output is in a highimpedance state
When system-fault happens, this output is in a highimpedance state.
For other normal conditions, this output is in a low
level(GND)
4 X30-OUT OUTPUT If residual current exceeds pre-set all-current tripping value (for pure-AC typically 23 mAAC), this output is in a high-impedance state.
When system-fault happens, this output is in a highimpedance state.
For other normal conditions, this output is in a low
level(GND)
5 GND POWER Ground
6 VDD POWER Module power supply, standard voltage 5VDC Voltage input required to be within 4.85~5.15VDC, power output capability > 100mA Power supply ripple ÿ 150mV (It is suggested to use LDO circuit, for reference IC LP2985A-50DB)
7 PWM OUTPUT Indicating DC residual current component with duty-cycle with 8kHz PWM Output resolution = 3.33%/mADC from 0~30mADC
Accuracy about ±0.5mA
