BASIC SPECIFICATIONS
For specifications that are not listed please contact Detroit Hoist for further information.
• Input power 3-phase 50/60hz (recommended).
• Single phase applica�ons must derate VFD to 70% and may require a larger VFD to supply the required motor current.
Please contact Detroit Hoist for further informa�on on single phase applica�ons.
• 380-480Vac (400v class models WJ-*****-HF).
• 208-240Vac (200v class models WJ-*****-LF).
• Digital I/O’s are 24vdc (27vdc max).
• Voltage fluctua�on must be -15% to +10% or less.
• Voltage imbalance must be ±3% or less.
• Frequency varia�on must be ±4% or less.
• Total harmonic distor�on (THD) of voltage must be ±10% or less.
• Ambient temperature -10 to 50℃ | 14 to 122 °f.
• In case of u�liza�on at an al�tude of 1000m or more, consider that the atmospheric pressure is reduced by 1% for every
100m up. Apply 1% dera�ng from the rated current by increasing every 100m and conduct an evalua�on test.
• IP20 – UL Open Type.
• Overload Current Ra�ng 150% 60sec / 200% 3sec.
• All Digital I/O is 24vdc.
• Suitable for use on a circuit capable of delivering not more than 5,000 rms symmetrical amperes.
• Integral solid state short circuit protec�on does not provide branch circuit protec�on. Branch circuit protec�on must be
provided in accordance with the Na�onal Electrical Code and any addi�onal local codes.
• Pollu�on degree 2 environment and Overvoltage category III.
• Built-in dynamic braking chopper circuit.
