Heyi Hyca B Type Current Sense Transformer in Electronic Wall Box EV Charger IEC62955

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.

Standard:

• HYCA type AC DC leakage current sensor Meet IEC 62752 mode II charging-related residual current test requirements.
• HYCA type AC DC leakage current sensor Meet IEC 62955 mode three charging RDC-PD related residual current test requirements.
• HYCA type AC DC leakage current sensor Meet the basic requirements of GB/T 22794 based on the adaptation of DC 6mA test requirements
