ZGGH15-24 Modular Power Supply Surge Protective Device
Product Specification
(For Reference Only)
General
The ZGGH15-24 Modular Power Supply SPD consists of a ZGGH15-24MK power supply module and a
ZGGH20-DZ1 base, used for secondary and tertiary protection of the DC system + — - and - — PE. It is
connected between DC power supply and system equipment in series or in parallel. It can prevent equipment
from the impulse surge and transient overvoltage caused by the outside environment (such as lightning, EMI,
etc.) or by the system (such as switching effects of the system, startup or shutoff of the inductance and
capacitance load, etc.).
Features
1 Anti-reverse slot design;
2 Low residual voltage;
3 Overtemperature protection;
4 Failure indication and central remote signalling alarm dry contact;
5 IP20, UL94 V0

Installation, Usage and Maintenance
Installation
1 This product can only be installed and maintained by qualified professionals. The installation position cannot
be touched by hands. Ensure that it is unpowered before installation.
2 The SPD should be installed behind the fuse (FU1) of the power supply circuit, with the capacity of the fuse
not exceeding 25A gL/gG; otherwise another fuse (FU2) should be provided in the surge protection branch
circuit.
3 Refer to Fig. 1, Fig. 2 and Fig. 3 for connection according to the marks on the SPD, with “Positive” to “+” of
SPD, “Negative” to “-” of SPD, and “ ” to PE. There are “IN” and “OUT” markings on the SPD, and the input
and output connections must be reliable.
4 Connection of remote signalling alarm: the SPD is provided with remote signalling alarm interfaces 11 and 12
(normally short-circuited; abnormally open), applicable for remote centralized monitoring or alarm.
5 After the connection, check if the module is fitted in before powered on. If normal, the “Green” indicator is on.

Usage and Maintenance
1 After failure, the ZGGH15-24 Modular Power Supply SPD shall be automatically disconnected with the power
supply circuit through the internal thermal fuse system, the working indicator in the display window is off, and
remote signalling interfaces 11 and 12 are closed. When the “Green” indicator is off or there’s a remote alarm
signal, the SPD should be changed immediately.
