1. Product Overview
The Cryomagtech High Precision Excitation Power Supply is a fully digital, high-performance bipolar constant current power supply designed for precise excitation of inductive loads such as superconducting magnets, electromagnets, and Helmholtz coils.
It delivers smooth, stable, and low-noise current control with continuous zero-crossing output and contactless commutation, ensuring an accurate and reliable magnetic field generation.
When integrated with an optional built-in Gauss meter, it provides a high-precision magnetic field platform for continuous field scanning, fast commutation, and current or magnetic field mode operation.
This power supply is a critical component for high-end laboratory and industrial magnetic field applications requiring exceptional stability, fast feedback, and quench protection.

2. Key Features
- Dual Control Modes ① Local Control: Touchscreen interface for direct parameter setting. ② Computer Control: USB or LAN connection for remote and efficient operation.
- Multiple Protection Functions ① Power failure protection (absorbs inductive backflow energy). ② Internal overheating protection (auto shutdown). ③ Overcurrent and overpower protection with automatic limitation and fault indication.
- Two Output Modes ① Current Mode: Directly set the load current. ② Magnetic Field Mode: Directly set the field intensity in magnets or coils. (Magnetic field mode requires the optional Cryomagtech high-precision Gauss meter.)
- Bipolar Output ① Four-quadrant operation for inductive loads. ② Smooth zero-crossing current without output switching. ③ Adjustable current change rate: 0.0007–0.5 Ir/s (Ir = rated maximum current).
- Superior Stability ① Current stability up to 5 ppm/h (ultra-high stability type). ② Excellent magnetic feedback and smooth output transitions.
- Wide Power Range ① Output power: 0.5 kW – 15 kW ② Output current: 5 A – 120 A ③ Output voltage: 40 V – 120 V
